\begin{Introduction}%%%%%%%%%%{documentation methods}

    This part of ISO 10303 specifies the \latex{} facilities specifically 
designed for use in preparing the various parts of this standard.

\begin{majorsublist}
\item the \file{step} package facility;
\item the \file{ir} package facility;
\item the \file{ap} package facility;
%%%\item the \file{am} package facility;
\item the \file{aic} package facility;
\item the \file{ats} package facility.
\end{majorsublist}

    This part of ISO~10303 is intended to be used in conjunction with
\textit{\latex{} for ISO standards: User manual}
which is based in part upon material in the ISO/IEC Directives,
Part 2 (\textit{Rules for the structure and drafting of International 
Standards, Fourth edition}).
The \latex{} facilities described here are based as well
upon the specifications given in ISO TC184/SC4 N1217n 
(\textit{SC4 Supplementary directives --- Rules for the structure
and drafting of SC4 standards for industrial data}).


\sclause*{Overview}


    This document describes a set of \latex{} macro files for use within
ISO~10303, commonly called STEP (STandard for the Exchange of Product
model data). The electronic source of this  document 
also provides an example of the use of these files.

    The current set of macro files have been developed by 
Peter Wilson (\url{peter.r.wilson@boeing.com}) from a macro file developed
by Kent Reed (NIST) for \latex{} v2.09. In turn, this was a revision of
files originally created by Phil Spiby (CADDETC), based on earlier work 
by Phil Kennicott (GE).\footnote{In mid 1994 \latex{} was upgraded 
from version 2.09 to what is called \latex 2e. The files described in 
this document are only applicable to \latex 2e (support for \latex{} v2.09
was dropped in September 1997).}


\begin{anote} 
It is important to remember that these macro files are only compatible with 
\latex 2e.
\end{anote} % end anote

    Documents produced with the \latex{} files have been twice reviewed 
by the ISO Editorial Board in Geneva for conformance to their 
typographical requirements. The first review was of a set of Draft 
International Standard documents. This review resulted in some changes 
to the style files. The second review was of a set of twelve 
International Standard documents (ISO 10303:1994). Likewise, this
review led to changes in the style files to bring the documents into 
conformance.

    With the issuance of the first STEP release, the opportunity was 
taken to provide a new baseline release of the package files. 
In particular, one STEP specific package file is available for all 
STEP parts, while others contain only commands relevant to the 
documentation of particular series of parts. The range of package 
files may be extended in the future to cater for 
documentation specific to all STEP parts.

   The 1997 baseline release was also designed to cater for the 
fact that a major update of \latex{} to \latex 2e took place during 1994.
\latex 2e is the only officially supported version of \latex.

    Because ISO standard documents have a very structured layout, the 
\file{isov2} class and the package files described here have been 
designed to reflect the logical document structure to a much greater 
extent than the `standard' \latex{} files. 

    With ISO's move toward accepting documents in PDF and HTML, 
the advent of second
editions of some of the STEP parts, and a new edition of the STEP
Supplementary Directives, a 2002
baseline release has been developed and is documented here.

\clause{Conformance requirements}  \label{sec:iconform}

    The facility files shall not be modified in any manner.

    If there is a need to modify any of the macro definitions then this
shall be done using the \latex{} 
\verb|\renewcommand|\ixcom{renewcommand} and/or the
\verb|\renewenvironment|\ixcom{renewenvironment}
commands. These shall be placed in a new \file{.sty} file (or files) 
which shall be called in within the preamble\index{preamble} of the 
document being typeset.

    There shall be no author specified \verb|\label{...}| commands where
the first two characters of the label are \verb|;s| (semicolon and `s');
the creation of labels starting with these characters is reserved to the 
maintainer of the facility files.

\begin{anote} For conformance to the \file{isov2} class, author specified
labels starting with the characters \verb|;i| (semicolon and `i') are
prohibited.
\end{anote}


\fcandaclause
%\clause{Fundamental concepts and assumptions}

    It is assumed that the reader of this document is familiar with the
\ixltx\latex{} document preparation system and in particular
with the \file{isov2}\ixclass{isov2} class and associated facilities 
described in 
\textit{LaTeX for ISO standards: User manual}.

\begin{note}Reference~\bref{lamport} describes the
      \latex{} system.
\end{note} % end note

    The reader is also assumed to be familiar with the ISO/IEC Directives 
Part~2 (ISOD)\index{ISOD} and
the SC4 Supplementary directives for the structure and drafting of 
SC4 standards (SD).\index{ISOD}\index{SD}

    If there are any discrepancies between the layout and wording of this 
document and the requirements of the ISOD or the SD,
then the requirements in those documents shall be
followed for ISO~10303 standard documents.

    The packages described herein have been designed to be used with
the \file{isov2}\ixclass{isov2} document class. It is highly unlikely that the
packages will perform at all with any other \latex{} document class.

    Because of many revisions over the years to the packages described
herein, a naming convention has been adopted for the package files.
The naming convention is that the
primary name of the file is suffixed by \file{v\#}, where
\file{\#} is the primary version number of the file in question.
All file primary names have been limited to a maximum of eight characters.

\begin{note}Table~\ref{tab:curfiles} shows the versions of the files
that were current at the time of publication.

\clearpage
\clause{The \file{step} package facility}

    The \file{step}\ixpack{step} package facility provides commands 
and environments 
applicable to all the ISO~10303 series of documents.

\sclause{Preamble commands}

    Certain commands shall be put in the preamble\index{preamble}
of any document.

    The command 
\verb|\partno{|\meta{number}\verb|}|\ixcom{partno}
is used to specify the Part number of the ISO~10303 standard
(e.g., \verb|\partno{3456}|).

    The command
\verb|\series{|\meta{series title}\verb|}|\ixcom{series}
is used to specify the name of the ISO~10303 series of which the Part 
is a member (e.g., \verb|\series{application modules}|).

    The command
\verb|\doctitle{|\meta{informal title}\verb|}|\ixcom{doctitle}
is used to specify the title to be used on the cover sheet.
For example: \\
\verb|\doctitle{LaTeX package files for ISO 10303: User manual}|

    The command
\verb|\ballotcycle{|\meta{number}\verb|}|\ixcom{ballotcycle}
is used to specify the ballot cycle number for the document
(e.g., \verb|\ballotcycle{2}|).

    The command\ixcom{ifhaspatents}
\verb|\haspatentstrue|\ixcom{haspatentstrue} shall be put in the
preamble when the document includes identified patented material;
otherwise the command \verb|\haspatentsfalse|\ixcom{haspatentsfalse}
may, but need not, be used instead.

    The \verb|\extrahead|\ixcom{extrahead} macro, from the \file{isov2}
class, shall be defined to be the document
number (e.g., \verb|\renewcommand{\extrahead}{47a}|).



\begin{anote}
The commands \verb|\standard|\ixcom{standard}, 
\verb|\yearofedition|\ixcom{yearofedition} and 
\verb|\languageofedition|\ixcom{languageofedition} from the \file{isov2}
class must also be put in the preamble.
\end{anote}

\sclause{Heading commands}

    The commands described in this subclause specify various `standard'
clause headings.

\ssclause{The Foreword commands}

    The \verb+\Foreword+\ixcom{Foreword} command specifies that a 
table of contents, list of figures and a list of tables be produced. 
Page numbering is roman style and the table of contents starts on page iii.
A new unnumbered clause entitled Foreword is started containing both 
ISO required boilerplate and boilerplate\index{boilerplate}
text specific to ISO 10303.


    Any text may be written after the \verb|\Foreword| command. The
Foreword clause is ended by the 
\verb+\endForeword{+\meta{norm annexes}\verb+}{+\meta{inf annexes}\verb+}+ 
command.\ixcom{endForeword} This command takes two parameters.
\begin{enumerate}
\item \meta{norm annexes} A phrase that starts the sentence 
      `\meta{norm annexes} a normative part of this part \ldots'.
     If there are no normative annexes, then use an empty
     argument (i.e., \verb|{}| with no spaces between the braces).
\item \meta{inf annexes} A phrase that starts the sentence 
     `\meta{inf annexes} for information only.'.
     If there are no informative annexes, then use an
     empty argument.
\end{enumerate}

    The \verb|\endForeword| command produces some additional 
boilerplate\index{boilerplate} text specifically for ISO 10303. 

\begin{example}
The \latex{} source for the Foreword for this document is:
\begin{verbatim}
\Foreword
\fwdshortlist
\endForeword
{Annexes A, B and C are}  % normative annexes
{Annexes D, E and F are} % informative annexes
\end{verbatim}
\end{example} % end example


    The \verb|\fwdshortlist|\ixcom{fwdshortlist} command 
produces boilerplate text for inclusion in the foreword referencing
the STEP parts and series. 
\begin{example}
In this document, the command \verb|\fwdshortlist| prints:

\fwdshortlist
\end{example}

    The \verb|\steptrid|\ixcom{steptrid} command
produces boilerplate text for inclusion in the foreword describing 
the creators of a STEP Technical Report.

\begin{example}
The \latex{} command \verb|\steptrid| in this document prints:
  
\steptrid
\end{example}


\ssclause{The Introduction environment}

    The 
\verb+\begin{Introduction}+\ixenv{Introduction}
environment starts a new unnumbered clause 
entitled Introduction and adds some boilerplate\index{boilerplate}
text specifically for ISO~10303.

\begin{example}
    The following \latex{} source was used to specify the Introduction 
to this document. \label{ex:intro}
\begin{verbatim}
\begin{Introduction}

    This part of ISO 10303 specifies the \latex{} facilities 
specifically designed for use in preparing the various parts of 
this standard.

\begin{majorsublist}
\item the \file{step} package facility;
\item the \file{ir} package facility;
\item the \file{ap} package facility;
\item the \file{aic} package facility;
\item the \file{atc} package facility.
\end{majorsublist}

    This part of ISO 10303 is intended to be used ...

\sclause*{Overview}

    This document describes a set of \latex{} files for use
within ISO~10303 ...

\end{Introduction}
\end{verbatim}
\end{example} % end example


\ssclause{The stepparttitle command}

   The \verb+\stepparttitle{+\meta{part title}\verb+}+\ixcom{stepparttitle}
command produces the title for
an ISO~10303 part, where \meta{part title} is the title of the part.

\begin{anexample}The title for this document was produced using:
\begin{verbatim}
\stepparttitle{Documentation methods:
               LaTeX package files for ISO 10303: User manual}
\end{verbatim}
\end{anexample} % end example


\ssclause{Other headings}

    Most of these commands take no parameters. They start document clauses
with particular titles. The commands that take no parameters are listed
in \tref{tab:noparamhead}. Some of these headings commands have predefined
labels, which are also listed in the table.
\ixcom{partidefhead}

\sclause{Miscellaneous commands}

    The following commands provide some printing options for commonly 
occurring situations. The \verb|\nexp{}|\ixcom{nexp} command is intended 
to be used for printing \Express{} \index{express@{\Express}} entity names etc.
\begin{itemize}
\item The command \verb|\B{abc}|\ixcom{B} prints \B{abc}
\item The command \verb|\E{abc}|\ixcom{E} prints \E{abc}
\item The command \verb|\Express|\ixcom{Express} prints \Express{}
\item The command \verb|\ExpressG|\ixcom{ExpressG} prints \ExpressG{}
\item The command \verb|\ExpressI|\ixcom{ExpressI} prints \ExpressI{}
\item The command \verb|\ExpressX|\ixcom{ExpressX} prints \ExpressX{}
\item The command \verb|\BG{|\meta{mathsymbol}\verb|}|\ixcom{BG} prints 
      \meta{mathsymbol} in bold font.
\item The command \verb|\HASH|\ixcom{HASH} prints \HASH{}
\item The command \verb|\LT|\ixcom{LT} prints \LT{}
\item The command \verb|\LE|\ixcom{LE} prints \LE{}
\item The command \verb|\NE|\ixcom{NE} prints \NE{}
\item The command \verb|\INE|\ixcom{INE} prints \INE{}
\item The command \verb|\GE|\ixcom{GE} prints \GE{}
\item The command \verb|\GT|\ixcom{GT} prints \GT{}
\item The command \verb|\CAT|\ixcom{CAT} prints \CAT{}
%\item The command \verb|\HAT|\ixcom{HAT} prints \HAT{}
\item The command \verb|\QUES|\ixcom{QUES} prints \QUES{}
%\item The command \verb|\BS|\ixcom{BS} prints \BS{}
\item The command \verb|\IEQ|\ixcom{IEQ} prints \IEQ{}
\item The command \verb|\INEQ|\ixcom{INEQ} prints \INEQ{}
\item The command \verb|\nexp{an\_entity}|\ixcom{nexp} prints \nexp{an\_entity}
\item The command \verb|\xword{ExpResS\_KeyworD}|\ixcom{xword}
      prints \xword{ExpResS\_KeyworD}
\end{itemize}

The command \verb|\ix{|\meta{word or phrase}\verb|}|\ixcom{ix} both prints 
its parameter and also makes an index entry out of it.

The command \verb|\mnote{|\meta{Marginal note text}\verb|}|\ixcom{mnote}
prints its parameter as a 
marginal note. \mnote{Quite a lot of marginal note text.}
Remember, though, that marginal notes are only printed when the 
\file{isov2}\ixclass{isov2} class \file{draft}\ixopt{draft} option
is used. Marginal notes are not allowed by ISO.

\ssclause{Standard reference commands}

    Many parts of STEP use the same normative or informative references.
The most common of these are provided via commands. The currently available 
commands are listed in \tref{tab:nrefc}.
\ixcom{nrefasni}
\ixcom{nrefparti}
\ixcom{nrefpartxi}
\ixcom{nrefpartxii}
\ixcom{nrefpartxxi}
\ixcom{nrefpartxxii}
\ixcom{nrefpartxxxi}
\ixcom{nrefpartxxxii}
\ixcom{nrefpartxli}
\ixcom{nrefpartxlii}
\ixcom{nrefpartxliii}

    The naming convention used for references to parts of ISO~10303 is to
end the command name with the number of the part expressed in lower case 
Roman numerals. Should further references to parts of ISO~10303 be added later, 
the same naming convention will be used.

\begin{table}
\centering
\caption{Commands for common references to standards} \label{tab:nrefc}

\end{table}


\begin{example} The normative references in this document were input as:
\begin{verbatim}
\begin{nreferences}
\isref{ISO/IEC Directives, Part 2}{Rules for the structure and drafting 
       International Standards, Fourth edition.}
\isref{...}
\nrefparti
\nrefpartxi
\nrefpartxii
\nrefasni
\disref{P. R. WILSON:---}{LaTeX for ISO standards: User manual.}
\end{nreferences}
\end{verbatim}
\end{example}

\begin{anote}
For the commands providing references to STEP parts, the part number 
is denoted by lowercase Roman numerals. Should further reference
commands be provided for other STEP parts, then the same naming scheme
will be used.
\end{anote}

    Some informative bibliographic reference commands are also provided.

The command \verb|\bibidefo|\ixcom{bibidefo} produces the reference
entry to the IDEF0 document and \verb|\brefidefo|\ixcom{brefidefo}
can be used for citing the reference in the body of the document.

The commands \verb|\bibidefix|\ixcom{bibidefix} and
\verb|\bibieeedefix|\ixcom{bibieeedefix} produce the reference entry
to the original FIPS version of IDEF1X and the IEEE version of IDEF1X
respectively. 
The command \verb|\brefidefix|\ixcom{brefidefix} can be used for
citing an IDEF1X reference in the body of the document.

   IDEF0 and IDEF1X are references \brefidefo{} and \brefidefix{}
in the bibliography.


\begin{example} Part of the bibliography for this document looks like:
\begin{verbatim}
\begin{references}
...
\reference{BRYAN, M.,}{SGML --- An Author's Guide to the Standard Generalized
           Markup Language,}{Addison-Wesley Publishing Co., 1988. }\label{bryan}
\bibidefo
\bibieeeidefix
\reference{RESSLER, S.,}{The National PDES Testbed Mail Server User's Guide,}

           Gaithersburg, MD 20899. January 1991.} \label{ressler}
...
\end{references}
\end{verbatim}
\end{example}

\begin{example}The source for one of the sentences above was:
\begin{verbatim}
IDEF0 and IDEF1X are references \brefidefo{} and \brefidefix{} in the bibliography.
\end{verbatim}
\end{example}

    
\sclause{Commands for documenting EXPRESS code} \index{express@\Express\}


    The Supplementary Directives\index{SD} specify the layout of the 
documentation of \Express{} code. The following commands are intended 
to serve two purposes:
\begin{enumerate}
\item To provide environments for the documentation of entity 
      attributes, etc.;
\item To provide begin and end tags around all the \Express{} code 
      documentation.
\end{enumerate}

    This latter purpose is to provide an enabling capability for the 
automatic extraction of portions of the documentation of an 
\Express{} model so that they could be placed into another document. 
For example, tools could be developed that would automatically extract 
pieces of resource model documentation and place them into an AP document.

\begin{anote}
This document uses the \file{hyphenat}\ixpack{hyphenat} 
package which enables automatic hyphenation of `words'
containing the underscore character command 
%(\verb|\_|\index{_/@\verb|\_|}). 
(\verb|\_|\index{_/@\texttt{\bs\_}}). 
Such words would normally have to
be coded as \verb|long\_\-word| to ensure potential hyphenation 
at the position of the underscore. When using the \file{hyphenat} package
it is an error to put the \verb|\-|\ixcom{-} discretionary
hyphen command after the underscore command as this then stops further
hyphenation.
\end{anote}


\ssclause{Environments ecode, eicode and excode}

    The \verb|ecode|\ixenv{ecode} environment is for 
tagging \Express{} code. It prints the appropriate title
and sets up the relevant fonts.

\begin{anexample} The following \latex{} source code:
\begin{verbatim}
\begin{ecode}\ixent{an\_entity}
\begin{verbatm}  % read verbatm as verbatim
*)
ENTITY an_entity;
  attr : REAL;
END_ENTITY;
(*
\end{verbatm}   % read verbatm as verbatim
\end{ecode}
\end{verbatim}

produces:

\begin{ecode}\ixent{an\_entity}
\begin{verbatim}
*)
ENTITY an_entity;
  attr : REAL;
END_ENTITY;
(*
\end{verbatim}
\end{ecode}
\end{anexample} % end example

    Similarly, the \verb|eicode|\ixenv{eicode} and
\verb|excode|\ixenv{excode} environments are for tagging \ExpressI{} 
and \ExpressX{} code and setting up the relevant titles and fonts.


\ssclause{Environment attrlist}

    The \verb|attrlist|\ixenv{attrlist} environment produces 
the heading for attribute definitions and sets up 
a \verb|description|\ixenv{description} list.

\begin{anexample}The following \latex{} source code:
\begin{verbatim}
\begin{attrlist}
\item[attr\_1] The \ldots
\item[attr\_2] This \ldots
\end{attrlist}
\end{verbatim}

produces:

\begin{attrlist}
\item[attr\_1] The \ldots
\item[attr\_2] This \ldots
\end{attrlist}
\end{anexample} % end example

\ssclause{Environment fproplist}

    The \verb|fproplist|\ixenv{fproplist} environment is similar to 
\verb|attrlist|\ixenv{attrlist} except that it is for
formal propositions.

\begin{anexample}The following \latex{} source code:
\begin{verbatim}
\begin{fproplist}
\item[un\_1] The value of \ldots\ shall be unique.
\item[gt\_0] The value of \ldots\ shall be greater than zero.
\end{fproplist}
\end{verbatim}

produces:

\begin{fproplist}
\item[un\_1] The value of \ldots\ shall be unique.
\item[gt\_0] The value of \ldots\ shall be greater than zero.
\end{fproplist}
\end{anexample} % end example

\ssclause{Other listing environments}

    The environments \verb|iproplist|\ixenv{iproplist}, 
\verb|enumlist|\ixenv{enumlist}, and \verb|arglist|\ixenv{arglist} are
similar to \verb|attrlist|\ixenv{attrlist}.
 Respectively they are environments for
informal propositions, enumerated items, and argument definitions.

\ssclause{Indexing}

    The command \verb|\ixent{|\meta{entity}\verb|}|\ixcom{ixent} 
generates an index
entry for the entity \meta{entity}.

    There are similar macros, each of which takes the name of the 
declaration as its argument, for indexing the other \Express{} declarations:
\verb|\ixenum|\ixcom{ixenum} for enumeration,
\verb|\ixfun|\ixcom{ixfun} for function,
\verb|\ixproc|\ixcom{ixproc} for procedure,
\verb|\ixrule|\ixcom{ixrule} for rule,
\verb|\ixsc|\ixcom{ixsc} for subtype\_constraint,
\verb|\ixschema|\ixcom{ixschema} for schema,
\verb|\ixselect|\ixcom{ixselect} for select, and
\verb|\ixtype|\ixcom{ixtype} for type.

\ssclause{Documentation tagging}

    Several environments are defined to tag the general documentation 
of \Express{} code. \index{express@\Express\}

    The environment \verb+\begin{espec}{+\meta{name}\verb+}+\ixenv{espec}
may be used to enclose, and give a name to, a complete specification 
block for an \Express{} entity. There are analogous environments --- 
\verb+fspec+\ixenv{fspec}, 
\verb+rspec+\ixenv{rspec}, 
\verb+sspec+\ixenv{sspec}, and
\verb+tspec+\ixenv{tspec} --- 
for functions, rules, schemas and types respectively.

    The \verb|dtext|\ixenv{dtext} environment may be used to anonymously 
enclose descriptive text.

\begin{example}\label{ex:code} Here is the suggested tagged documentation 
style for part of an \Express{} model.
\begin{verbatim}
%\ssclause{committee\_def}
\begin{espec}{committee_def}
\begin{dtext}
    A committee is composed of an odd number of people. 
Each committee also has a name.
    The ideal size of a committee is less than three.

\begin{anote} Figures and tables may also be placed here. \end{anote} % end note
\end{dtext}
\begin{ecode}\ixent{committee\_def}
\begin{verbatm} % read verbatm as verbatim

  odd_members : ODD(SIZEOF(members));
END_ENTITY;
(*
\end{verbatm}   % read verbatm as verbatim
\end{ecode}
\begin{attrlist}
\item[title] The name of the committee.
\item[members] The people who form the committee.
\item[ideal] TRUE if there is only one person 
             on the committee.
             That is, if the committee is the ideal size.
\end{attrlist}
\begin{fproplist}
\item[un1] The \nexp{title} of the committee shall be unique.
\item[odd\_members] There shall be an odd number of people 
                    on the committee.
\end{fproplist}
\begin{iproplist}
\item[chair] The members of a committee shall appoint one of 
             their number as
             chair of the committee.
\end{iproplist}
\end{espec}
\end{verbatim}
\end{example} % end example

\begin{example}
The code in \eref{ex:code} produces the following result:

\begin{espec}{committee_def}
\begin{dtext}
    A committee is composed of an odd number of people. 
Each committee also has a name.
The ideal size of a committee is less than three.

\begin{anote} Figures and tables may also be placed here. \end{anote} % end note

\sclause{Commands producing boilerplate text} \index{boilerplate}

    The following commands produce boilerplate text as specified by the 
Supplementary Directives\index{SD}.

\begin{anote}
 In the examples, 
the parameters of those commands that
take them have been specified in 
\textit{this font style} so their effects can
be seen in the resulting printed text.
\end{anote}

\ssclause{Definition of \ExpressG}

    The \verb|\expressgdef|\ixcom{expressgdef} prints the boilerplate
for where the definition of \ExpressG{} can be found.

\begin{anexample}
The command \verb|\expressgdef| prints: 

\expressgdef
\end{anexample} 

\ssclause{Major subdivision listing}

    The \verb|majorsublist|\ixenv{majorsublist}
environment prints the boilerplate for the heading of a listing of
major subdivisions of the standard and starts an itemized list.
An illustration of its use is given in \eref{ex:intro} 
on page~\pageref{ex:intro}.

The heading text is produced by the 
\verb|\majorsubname|\ixcom{majorsubname} command.

\begin{anexample} The command \verb|\majorsubname| command prints:

\majorsubname

\end{anexample}

\ssclause{Schema introduction}

    The command \verb|\schemahead{|\meta{schema name}\verb|}|\ixcom{schemahead} prints the heading for a schema clause.

    The command \verb+\schemaintro{+\meta{schema name}\verb+}+\ixcom{schemaintro} 
produces the boilerplate for the introduction to an \Express{} schema
clause.

\begin{anexample}The command \verb|\schemaintro{\nexp{this\_schema}}| prints:

\schemaintro{\nexp{this\_schema}}
\end{anexample}
  


\ssclause{Short names of entities}

    The command \verb|\shortnamehead|\ixcom{shortnamehead} prints the
heading for the short names annex.

    The command \verb|\shortnames|\ixcom{shortnames} 
produces the boilerplate for the
introduction to the annex listing short names.

\begin{anexample}The command \verb|\shortnames| prints:

\shortnames 
\end{anexample} %end example

\ssclause{Registration commands}

    The command \verb|\objreghead|\ixcom{objreghead} prints the heading
for the information object registration annex.

    The command \verb|\docidhead|\ixcom{docidhead} prints the heading
for the document identification subclause.


    The command 
\verb+\docreg{+\meta{version no}\verb+}+\ixcom{docreg}

\verb+\APtitle{+\meta{title of AP}\verb+}+\ixcom{APtitle} shall be put 
in the preamble,
where \meta{title of AP} is the ISO 10303 part title of the
corresponding AP. This must be given in such a manner that it reads
sensibly in a sentence of the form `\ldots for ISO 10303-299,
application protocol \meta{title of AP}.'

\begin{example}
For the purposes of later examples, the command
\verb+\APtitle{+\texttt{\theAPtitle}\verb+}+ 
has been put in the preamble of this document.
\end{example}

    The command
\verb+\mapspectrue+\ixcom{mapspectrue}
shall be put in the preamble if the AP uses a mapping specification rather
than a mapping table.

% sgmlannx.tex    latex and SGML

\infannex{LaTeX, the Web, and *ML} \label{anx:sgml} \index{SGML}

    ISO are becoming more interested in electronic sources for their
standards as well as the traditional camera-ready copy. Acronyms like
PDF, HTML, SGML and XML have been bandied about. Fortunately documents
written using \latex{} are well placed to be provided in a variety of 
electronic formats. A comprehensive treatment of \latex{} with respect
to this topic is provided by Goossens and Rahtz~\bref{lwebcom}.

    SGML (Standard Generalized Markup Language) is a document tagging 
language that is described in ISO~8879~\bref{sgml} and whose usage is described 
in~\bref{bryan}, among others. The principal
mover behind SGML is Charles Goldfarb from IBM, who has authored a detailed 
handbook~\bref{goldfarb} on the SGML standard.

    The concepts lying behind both \latex{} and SGML are similar, but on the face
of it they are distinctly different in both syntax and capabilities. ISO is
migrating towards electronic versions of its standard documents and, naturally, 
would prefer these to be SGML tagged. 
     Like \latex, SGML has a
concept of style files, which are termed DTDs, and both systems support
powerful macro-like capabilities. SGML provides for logical document
markup and not typesetting --- commercial SGML systems often use
\tex{} or \latex{} as their printing engine, as does the NIST SGML
environment for ISO~10303~\bref{pandl}.



NIST have SGML tagged some STEP documents 
using manual methods, which are time consuming and expensive. 
In about 1997 there was a NIST 
effort underway to develop an auto-tagger that would (semi-) automatically 
convert
a \latex{} tagged document to one with SGML tags. This tool assumed a
fixed set of \latex{} macros and a fixed DTD.
 The design of an auto-tagger
essentially boils down to being able to convert from a source document tagged
according to a \latex{} style file to one which is tagged according to an
SGML DTD.
    Fully automatic conversion is really only possible if the authors'
of the documents to be translated avoid using any `non-standard' macros within
their documents. There is a program called \file{ltx2x}\index{ltx2x} available
from SOLIS, which replaces \latex{} commands within a document with
user-defined text strings~\bref{ltx2x}. This can be used as a basis for
a \latex{} to whatever auto-tagger, provided the \latex{} commands are not
too exotic.

    HTML is a simple markup language, based on SGML, and is used for the
publication of many documents on the Web. XML is a subset of SGML and appears
to being taken up by every man and his dog as \emph{the} document markup
language. HTML is being recast in terms of XML instead of SGML. PDF is a page
description language that is a popular format for display of documents 
on the Web.

    \latex{} documents can be output in PDF by using pdfLaTeX. Instead
of a \file{.dvi} file being produced a \file{.pdf} file is output directly.
The best 
results are obtained when PostScript fonts rather than Knuth's cm fonts 
are used. Noting that the \file{isov2} class provides an \verb|\ifpdf| command,
a general form for documents to be processed by either \latex{} or pdfLaTeX
is
\begin{verbatim}
\documentclass{isov2}
\usepackage{times}     % PostScript fonts Times, Courier, Helvetica
\ifpdf
  \pdfoutput=1         % request PDF output
  \usepackage[pdftex]{graphicx}
\else
  \usepackage{graphicx}
\fi
...
\end{verbatim}

    There are several converters available to transform a \latex{} document 
into an HTML document, but like \file{ltx2x} they generally do their own
parsing of the source file, and unlike \file{ltx2x} are typically limited
to only generating HTML. Eitan Gurari's \file{TeX4ht}\index{TeX4ht} 
suite is a notable
exception (see Chapter~4 and Appendix~B of~\bref{lwebcom}). It uses the 
\file{.dvi} file as input, so that all the parsing is done by \tex, and can be
configured to generate a wide variety of output formats.
A set of \file{TeX4ht} configuration files are available for converting
STEP \latex{} documents into HTML\footnote{Later, configuration files for XML
output will be developed.}.

    It is highly recommended that for the purposes of ISO~10303, document editors
refrain from defining their own \latex{} macros. If new generally applicable
\latex{} commands are found to be necessary, these should be sent to the
editor of this document for incorporation into
the \file{isov2}\ixclass{isov2} class, the \file{step}\ixpack{step}
package and/or appropriate other packages.

    Some other points to watch when writing \latex{} documents that will assist
in translations into *ML are given below. Typically, attention to these points
will make it easier to parse the \latex{} source.

\begin{itemize}
\item Avoid using the \verb|\label|\ixcom{label} command within
      clause headings or captions. It can just as easily be placed immediately
      after these constructs.
\item Avoid using the \verb|\index|\ixcom{index} command within
      clause headings or captions. It can just as easily be placed immediately
      after these constructs.
\item Use all the specified tagging constructs when defining an \Express{} 
      model --- this will also assist any program that attempts to extract
      \Express{} source code and descriptive text from a document.
\end{itemize}



\infannex{Obtaining LaTeX and friends} \label{anx:getstuff}

    \latex{} is a freely available document typesetting system. There are many
public domain additions to the basic system, for example the \file{iso.cls}
and \file{step.sty} styles. The information below gives pointers to where
you can obtain \latex{} etc., from the\index{Internet} Internet. 


    \latex{} runs on a wide variety of hardware, from PCs to Crays. Source to build
a \latex{} system is freely available via anonymous ftp\index{ftp} 
from what is called CTAN\index{CTAN}
(Comprehensive \tex\ Archive Network). 
There are three sites; pick the one nearest to you.
\begin{itemize}
\item \url{ftp.dante.de} CTAN in Germany;
\item \url{ftp.tex.ac.uk} CTAN in the UK;
\item \url{ctan.tug.org} CTAN in the USA;
\end{itemize}
The top level CTAN directory 
for \latex{} and friends is \url{/tex-archive}. CTAN contains a wide variety
of (La)TeX sources, style files, and software tools and scripts to assist in
document processing.

\begin{anote}
CTAN is maintained by the \tex{} Users Group (TUG). Their homepage
\isourl{http://www.tug.org} should be consulted for the current list of CTAN sites and mirrors.

\sclause{SOLIS} \index{SOLIS}

    SOLIS is the \textit{SC4 On Line Information Service}. It contains many electronic
sources of STEP related documents. The relevant top level directory is
\url{pub/subject/sc4}.
 In particular, SOLIS contains the source for this document
and the \file{.sty} files, as well as other \latex{} related files. 
The \latex{} root directory is \url{sc4/editing/latex}.
The latest versions of the \latex{}
related files are kept in the sub-directory \url{latex/current}.
Some \latex{} related programs are also available in the 
\url{latex/programs} sub-directory.

    There are several ways of accessing SOLIS; instructions
are detailed by Ressler~\bref{ressler} and Rinaudot~\bref{rinaudot}. 
Copies of these reports may be obtained by telephoning the
IPO Office at \verb|+1 (301) 975-3983|, although they are probably somewhat
dated by now.
The simplest method is to point your browser at the following URL: \\
