+    The iso class is for typesetting ISO International Standard documents
+according to the requirements specified in "ISO/IEC Directives, Part 2,
+Rules for the structure and drafting of International Standards.
+(Fourth edition, 2001)". Configuration files for TeX4ht are also provided.
+
+Changes in the 2002 release
+o Updated from ISO/IEC Directives, Third edition, 1997 to the 
+  Fourth edition, 2001.
+
+    The distribution is under the LPPL and consists of the following files:
+README (this file)
+isoe.dtx
+isoe.ins
+iso4ht.dtx
+iso4ht.ins
+isoman.tex
+isoman.pdf
+isoman.ps
+
+  To install the class (and packages)
+o run: latex isoe.ins (which will generate *.cls, *.clo, *.sty and *.tex files)
+o Optionally, to print the commented source code
+  o run: latex isoe.dtx
+  o run: makeindex -s gind.ist isoe
+  o run: latex isoe.dtx
+  o print isoe.dvi for a hardcopy
+o Move the generated files to a location where LaTeX will find them
+  (if you don't know where this is, see the FAQ on CTAN in /help/uktug-faq)
+o For the User Manual, either latex isoman.tex or print isoman.pdf or
+  isoman.ps
+
+o If you might use TeX4ht:
+  o run: latex iso4ht.dtx (which will generate *.4ht file(s))
+  o To print the commented source code, follow instructions above on iso4ht.dtx
+  o Move the generated *.4ht file(s) to a location where TeX4ht will find them
+
+    Don't forget to update the (La)TeX file database if you have one.

+\begin{introduction}
+
+    This document describes the use of the \file{isov2} \latex{} class 
+file and some package files in preparing ISO standard documents.
+
+\sclause*{Overview}
+
+    This document describes a \latex{} class file, called \file{isov2},
+ for typesetting ISO standards. It also
+provides descriptions of some particular package files (e.g., \file{isorot}) 
+that have been developed to support the writing of ISO standards.
+The electronic source of this  document also provides an example of the
+use of these files.
+
+
+
+    The current set of files~\bref{isoe} have been developed by 
+Peter Wilson (RPI, CUA and NIST, Boeing)
+from files written by Kent Reed (NIST).
+In turn, these were revisions of files originally created by 
+Phil Spiby (CADDETC, UK), based on early 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 
+earlier versions this document were compatible with both versions 
+of \latex. Starting with the October 1997 release, 
+support was withdrawn from any \latex{} v2.09 file versions.}
+
+
+    Documents produced with the \latex{} files have been reviewed 
+by the ISO Editorial Board in Geneva for conformance to their typographical
+requirements. The first review was of a series of Draft International 
+Standard documents. This review resulted in some changes to the style 
+files. The second review was of a series of twelve International Standard 
+documents (ISO 10303:1994). Likewise, this review led to changes in the 
+style files to bring the documents into compliance.
+
+    With the publication of the ISO~10303:1994 standard, the opportunity 
+was taken
+to provide a new baseline release of the package files.
+The new baseline release was also designed to address the fact that
+a major update of \latex{} to \latex 2e took place during 1994. \latex 2e
+is now the officially supported version. However, some users needed time
+to convert to using \latex 2e. Consequently, although the 
+facilities described in the original version of this document 
+were common for both 
+\latex{} v2.09 and \latex 2e users, there were two different 
+implementations.
+
+    Because ISO standard documents have a very structured layout, the class
+and package files have been designed to reflect the logical document structure
+to a much greater extent than the `standard' \latex{} files. Further, ISO
+documents are published in more than one language. The files described
+here are written for the English language, but the language-specific elements
+have been parameterized for easy modification for publication in other
+official ISO languages, such as French.
+
+    In 1997 ISO produced a new version of their Directives on the 
+requirements for the layout of ISO documents. These were not completely
+unambiguous as to their intent; the current version was released in
+2001. Members of ISO TC184/SC4 have worked with
+the ISO Editorial Board and have reached an agreement that more precisely
+identifies the requirements. The current version of the \latex{} files 
+implements that agreement.

+\begin{note}Reference~\bref{lamport} in the bibliography describes the
+      \latex{} system.
+\end{note}
+
+    The reader is also assumed to be familiar with the ISO/IEC Directives

+and ISO TC184/SC4 are documented in the SC4 Supplementary Directives
+(SD\index{SD}).
+
+    If there are any discrepancies between the layout and wording of this

+
+\begin{note}
+Additional \latex{} facilities specifically designed for ISO~10303 are
+defined and described elsewhere~\bref{stepsty}.
+\end{note}
+
+    Because of many revisions over the years to the files described
+herein, a naming convention has been adopted for them.
+The primary name of the file is suffixed by \file{v\#} or \file{\#}, where
+\file{\#} is the version number of the file in question. 
+All file primary names have been limited to a 
+maximum of eight characters.

+\clause{The \file{iso} class facility} 
+
+    The \latex{} \file{isov2}\ixclass{isov2} class file
+is a general file for use in preparing ISO
+standard documents using the \latex{} document preparation system.
+
+    As usual, any \latex{} document has the following structure:
+\begin{verbatim}
+\documentclass[<list of options>]{isov2}
+% preamble goes here
+\begin{document}
+% document body goes here
+\end{document}
+\end{verbatim}
+
+\sclause{Options}
+
+    The \file{isov2}\ixclass{isov2} class file supports the following options: 
+\begin{itemize}
+\item \verb|draft|\ixopt{draft} for a draft document where 
+      overfull horizontal boxes are marked, marginal notes are allowed,
+      and ISO copyright text is not placed in the document;
+\item \verb|final|\ixopt{final} the opposite of \verb|draft|
+      (this is the default);
+\item \verb|letterpaper|\ixopt{letterpaper} for printing 
+      on US letter size paper;
+\item \verb|a4paper|\ixopt{a4paper} for printing on A4
+      size paper (this is the default);
+\item \verb|twocolumn|\ixopt{twocolumn} for two column 
+      formatting;
+\item \verb|onecolumn|\ixopt{onecolumn} for single column
+      printing (this is the default);
+\item One of \verb|11pt|, \ixopt{11pt}
+      \verb|10pt|, \ixopt{10pt}
+      \verb|9pt|\ixopt{9pt} for 11pt, 10pt or 9pt printing
+      respectively (the default is \verb|11pt|);
+\item \verb|notcopyright|\ixopt{notcopyright} for 
+      disabling the printing of copyright notices (this is the default);
+\item \verb|copyright|\ixopt{copyright} enables printing
+      of copyright notices;
+\item \verb|is|\ixopt{is} for International Standard documents;
+\item \verb|fdis|\ixopt{fdis} for  Final Draft
+      International Standard documents; \index{FDIS}
+\item \verb|dis|\ixopt{dis} for  Draft
+      International Standard documents; \index{DIS}
+\item \verb|cd|\ixopt{cd} for  Committee Draft
+      standard documents; \index{CD}
+\item \verb|wd|\ixopt{wd} for  Working Draft
+      standard documents; \index{WD}
+\item \verb|pas|\ixopt{pas} for Publicly Available Specification
+      standard documents;
+\item \verb|techrep|\ixopt{techrep} for Technical
+      Report standard documents; \index{TR}
+\item \verb|techspec|\ixopt{techspec} for Technical
+      Spefication standard documents; \index{TS}
+\item \verb|otherdoc|\ixopt{otherdoc} for documents
+      that are not intended to become a standard (this is the default);
+%\item \verb|uglycaption|\ixopt{uglycaption} to produce
+%      an ugly style of captioning;
+\item Any other facilities that are available via packages.
+\end{itemize}
+
+    When no options are specified, then the result is 11pt, single column
+printing on A4 size paper, without copyright notice and a running header.
+That is, by default, the options set are: 
+\verb|final|\ixopt{final};
+\verb|a4paper|\ixopt{a4paper}; 
+\verb|onecolumn|\ixopt{onecolumn};
+\verb|11pt|\ixopt{11pt};
+\verb|notcopyright|\ixopt{notcopyright}; and
+\verb|otherdoc|\ixopt{otherdoc}.
+
+
+%\begin{note}ISOD\index{ISOD} calls for 9pt double column  printing but the 
+%      SD\index{SD} calls for 11pt single column printing.
+%      Using 9pt double column printing is awkward if any computer 
+%      code has to
+%      be typeset in the document. The IS-REVIEW\index{IS-REVIEW} accepted
+%      11pt single column layout. \end{note} % end note
+%\begin{note}The CRC\index{CRC} states that acceptable founts are: Univers,
+%    Helvetica, and Times Roman with the body text in 10pt. 
+%    The IS-REVIEW accepted camera-ready copy
+%    using Computer Modern 11pt set in single column. \end{note}
+\begin{note}The user of the \file{isov2}\ixclass{isov2} class is encouraged 
+      to process this document using
+      different combinations of the options to gain experience with
+      their effects. This printing of the document is typeset using the
+      \verb|draft|\ixopt{draft} option.
+\end{note} % end note
+\begin{note}
+    The \verb|otherdoc|\ixopt{otherdoc} option 
+was chosen as the default so that the
+current stage of ISO standardardization has to be explicitly declared
+as an option, and is therefore available to any software package that
+might process the document source (e.g., a \latex{} to SGML translator).
+\end{note}
+
+
+\sclause{Sectioning commands}
+
+    Table~\ref{tab:sec} gives the sectioning commands defined for \file{isov2}

+\item \verb+\infannex{+\meta{title}\verb+}+\ixcom{infannex}
+       for an informative annex;
+\item \verb+\repannex{+\meta{title}\verb+}+\ixcom{repannex}
+      for an annex that is neither normative or
+     informative (e.g. an annex in a technical report).
+\end{itemize}
+
+    Only \verb|\sclause|\ixcom{sclause} and lower level 
+sectioning commands can be used after
+an annex\index{annex} command.
+
+
+\begin{example}
+    The command  \verb|\infannex{Technical discussion}|, assuming that this is the first
+annex in the document, produces:
+    \begin{center}
+    \textbf{Annex A}\\
+    (informative)
+
+    \textbf{Technical discussion}
+    \end{center}
+\end{example} % end example
+\begin{example}
+  The command \verb|\repannex{Title of annex}|, assuming that this is the second
+annex in the document, produces:
+
+\begin{center}
+  \textbf{Annex B}
+
+  \textbf{Title of annex}
+\end{center}
+\end{example} % end example
+
+
+\ssclause{The use of \texttt{tocdepth} and \texttt{secnumdepth}}
+
+    In the standard \latex{} classes the
+\verb|tocdepth|\ixtt{tocdepth} and 
+\verb|secnumdepth|\ixtt{secnumdepth} counters
+are set in the preamble\index{preamble} to respectively control the level at
+which clause titles are inserted into a table of contents (ToC)\index{ToC} 
+and at which clause numbering ceases.
+
+    In the \file{isov2}\ixclass{isov2} class, 
+the values of these can be changed at 
+any point in the document. The change lasts until another change is
+made to the value. 
+\begin{example}
+    Assume that in the preamble we have
+\begin{verbatim}
+\setcounter{secnumdepth}{3}  % number ssclauses and above
+\setcounter{tocdepth}{3}     % ToC includes ssclauses and above
+\end{verbatim}
+and that a certain subclause has subsubclauses that should be numbered but
+not put into the table of contents, then we could do:
+\begin{verbatim}
+...
+\sclause{The certain subclause}
+\setcounter{tocdepth}{2}
+...
+\ssclause{Numbered but not in ToC}
+...
+...
+\setcounter{tocdepth}{3}
+\sclause{Following subclause}
+\end{verbatim}
+
+\end{example}
+
+    It can sometimes be difficult to remember which level number corresponds
+to which kind of clause. Accordingly, a set of commands are provided to ease
+this task. These commands can only be used after the preamble.
+\begin{itemize}
+\item \verb|\maxsecnumdepth{|\meta{sec}\verb|}|\ixcom{maxsecnumdepth}
+      sets the level at which clauses will be numbered. This command
+      should be used before the first sectioning command.
+\item \verb|\maxtocdepth{|\meta{sec}\verb|}|\ixcom{maxtocdepth}
+      sets the level at which clauses will be put into the ToC.
+      This command should be used before the \verb|\tableofcontents| command.
+\item \verb|\setsecnumdepth{|\meta{sec}\verb|}|\ixcom{setsecnumdepth}
+      sets the current level at which clauses will be numbered. 
+      This command can be used anywhere after the preamble.
+\item \verb|\settocdepth{|\meta{sec}\verb|}|\ixcom{settocdepth}
+      sets the current level at which clauses will put into the ToC. 
+      This command can be used anywhere after the preamble.
+\end{itemize}
+The value of the argument \meta{sec} can be any of the following:
+\texttt{clause}, \texttt{sclause}, \ldots, \texttt{sssssclause}.
+
+\begin{example}
+Using these commands, the previous example can also be coded as:
+\begin{verbatim}
+...
+\begin{document}
+\maxsecnumdepth{ssclause}
+\maxtocdepth{ssclause}
+...
+\sclause{The certain subclause}
+\settocdepth{sclause}
+...
+\ssclause{Numbered but not in ToC}
+...
+...
+\settocdepth{ssclause}
+\sclause{Following subclause}
+\end{verbatim}
+
+\end{example}
+
+
+
+\sclause{LaTeX environments and commands}
+
+    Many of the standard \latex{} environments and commands are available.
+In particular, all the normal mathematical typesetting capabilities are
+present.
+However, there are some additional environments and commands defined.
+
+\ssclause{Lists}
+
+    The standard \latex{} \verb|itemize|,\ixenv{itemize}
+\verb|enumerate|\ixenv{enumerate} and \verb|description|\ixenv{description}
+environments are provided. The labels in these lists, though, differ from
+those normally provided by \latex.
+
+\begin{note}
+The ISOD describes only a single level for an itemized list, being marked 
+with either an em-dash or a bullet. The SD deprecates the bullet but 
+provides four levels, each being marked with an em-dash. These are 
+provided in the \file{isov2} class.
+\end{note}
+\begin{note}
+The ISOD allows for two levels of enumerated lists. The SD extends this
+to four levels, and these are provided in the \file{isov2} class.
+\end{note}
+
+\begin{example}
+The list environments provided are shown below as:\ixenv{itemize}
+\begin{verbatim}
+\begin{itemize}
+\item First level itemized element;
+  \begin{itemize}
+  \item Second level itemized element;
+    \begin{itemize}
+    \item Third level itemized element;
+      \begin{itemize}
+      \item Fourth level itemized element.
+      \end{itemize}
+    \end{itemize}
+  \end{itemize}
+\end{itemize}
+\end{verbatim}
+
+\ixenv{enumerate}
+\begin{verbatim}
+\begin{enumerate}
+\item First level enumerated element;
+  \begin{enumerate}
+  \item Second level enumerated element;
+    \begin{enumerate}
+    \item Third level enumerated element;
+      \begin{enumerate}
+      \item Fourth level enumerated element.
+      \end{enumerate}
+    \end{enumerate}
+  \end{enumerate}
+\end{enumerate}
+\end{verbatim}
+
+\ixenv{description}
+\begin{verbatim}
+\begin{description}
+\item[Description] a description element. Note that a colon is
+                   automatically added to the item label.
+\end{description}
+\end{verbatim}
+and they produce
+\begin{itemize}
+\item First level itemized element;
+  \begin{itemize}
+  \item Second level itemized element;
+    \begin{itemize}
+    \item Third level itemized element;
+      \begin{itemize}
+      \item Fourth level itemized element.
+      \end{itemize}
+    \end{itemize}
+  \end{itemize}
+\end{itemize}
+
+\begin{enumerate}
+\item First level enumerated element;
+  \begin{enumerate}
+  \item Second level enumerated element;
+    \begin{enumerate}
+    \item Third level enumerated element;
+      \begin{enumerate}
+      \item Fourth level enumerated element.
+      \end{enumerate}
+    \end{enumerate}
+  \end{enumerate}
+\end{enumerate}
+
+\begin{description}
+\item[Description] a description element. Note that a colon is
+                   automatically added to the item label.
+\end{description}
+
+\end{example} % end example
+
+\begin{example}
+    Here is a more complex set of lists:
+
+\begin{itemize}
+\item First level itemization
+  \begin{enumerate}
+  \item First level enumeration
+    \begin{itemize}
+    \item Second level itemization
+      \begin{enumerate}
+      \item Second level enumeration
+        \begin{itemize}
+        \item Third level itemization
+%          \begin{enumerate}    % At this point the list is too deeply nested.
+%          \item Third level enumeration    % For the TeXnophile this is
+%          \item 3rd level enumeration      % because the example environment
+%         \end{enumerate}                   % is itself a list.
+        \item 3rd level itemization
+        \end{itemize}
+      \item 2nd level enumeration
+      \end{enumerate}
+    \item 2nd level itemization
+    \end{itemize}
+  \item 1st level enumeration
+  \end{enumerate}
+\item 1st level itemization
+\end{itemize}
+
+\end{example} % end example
+
+\begin{note}
+On occasion, \latex{} objects to a well formed list. Typically, this happens
+when a list has only one entry. \index{list!error}
+ The \latex{} error message is of the form:
+\begin{verbatim}
+! Something's wrong--perhaps a missing \item.
+\end{verbatim}
+Hitting the \verb|<return>| key usually gets \latex{} to run on happily.
+\end{note}% end note
+\begin{note}
+Similarly, you may get the message
+\begin{verbatim}
+! Too deeply nested
+\end{verbatim}
+Again, hit \verb|<return>| and processing should continue. However,
+the indentation of later lists may not be correct.
+\end{note} % end note
+
+
+\ssclause{Notes}
+
+    
+    Two different kinds of environments are provided for typesetting notes.
+
+\sssclause{Numbered notes}
+
+    The environment 
+\verb+\begin{note}+ \meta{text} \verb+\end{note}+\ixenv{note}
+produces a numbered note whose body consists
+of \meta{text}.
+
+\begin{anexample}
+The commands
+\begin{verbatim}
+\begin{note}Numbered note.\end{note}
+\end{verbatim}
+produce
+
+\begin{note}Numbered note.\end{note}
+\end{anexample}
+
+\sssclause{Isolated notes}
+
+    The environment 
+\verb+\begin{anote}+ \meta{text} \verb+\end{anote}+\ixenv{anote}
+produces an un-numbered note whose body
+consists of \meta{text}.
+
+\begin{anexample}
+    The commands
+\begin{verbatim}
+\begin{anote}Plain note.\end{anote}
+\end{verbatim}
+produce
+
+\begin{anote}Plain note.\end{anote}
+\end{anexample} % end example
+
+
+\ssclause{Examples} \label{ssc:ex}
+
+    Two different kinds of environments are provided for typesetting 
+examples.
+
+\sssclause{Numbered examples} \label{cl:numex}
+
+The environment \verb?\begin{example}? \meta{text} \verb?\end{example}?
+produces a numbered example whose body consists of \meta{text}.
+
+\begin{anexample}
+The commands
+\begin{verbatim}
+\begin{example}Numbered example. \label{ex:exref} \end{example}
+\end{verbatim}
+produce
+
+\begin{example}Numbered example. \label{ex:exref} \end{example}
+\end{anexample}
+
+\begin{anote}
+Numbered examples (and numbered notes) may be identified using the
+\verb?\label{...}?\ixcom{label} command, as exhibited in \eref{ex:exref}
+in \ref{cl:numex}, and then referred to by the 
+\verb?\ref{...}?\ixcom{ref} command.
+\end{anote}
+
+\sssclause{Isolated examples}
+
+The environment \verb?\begin{anexample}? \meta{text} \verb?\end{anexample}?
+produces an un-numbered example whose body consists of \meta{text}.
+\ixenv{anexample}
+
+\begin{anexample}
+The commands
+\begin{verbatim}
+\begin{anexample}Isolated example.\end{anexample}
+\end{verbatim}
+produce
+
+\begin{anexample}Isolated example.\end{anexample}
+\end{anexample}
+
+
+
+\ssclause{Bibliographic references}
+
+    Two different kinds of environments are provided for bibliographic 
+references. It should be noted that neither of these has anything to do with
+BibTeX.\index{BibTeX}
+
+\sssclause{Normative references}
+
+    Normative references are listed in the 
+\verb|nreferences|\ixenv{nreferences} environment.
+
+    In this environment, bibliographic entries are denoted by either
+\verb+\isref{+\meta{ref}\verb+}{+\meta{title}\verb+}+ or by 
+\verb+\disref{+\meta{ref}\verb+}{+\meta{title}\verb+}+. The
+\meta{ref} parameter is the number of the standard document and 
+the \meta{title} parameter is the title of the standard. 
+
+    Use the \verb|\isref|\ixcom{isref} command for published standards 
+and the \verb|\disref|\ixcom{disref}
+ command for documents that have not yet been 
+finally approved as a standard. This latter command automatically adds a
+footnote to the effect  that the document is
+to be published.
+
+\begin{example}
+The \latex{} source for the references in clause~\ref{sec:nrefs} of 
+this document is:
+\begin{verbatim}
+\begin{nreferences}
+\isref{ISO/IEC Directives, Part 2}{Rules for the structure and drafting of
+       International Standards. (Fourth edition, 2001)}
+...
+...
+\disref{ISO}{Camera-ready copy (CRC) ---
+       Submission requirements and ISO type specification.
+       (Version 1.0, 1996-04-26)}
+\end{nreferences}
+\end{verbatim}
+\end{example} % end example
+
+
+\sssclause{Informative references}
+
+    Informative bibliography elements are listed in the
+\verb|references|\ixenv{references} environment. 
+Each element in the list is specified as 
+\verb+\reference{+\meta{author}\verb+}{+\meta{title}\verb+}{+\meta{publisher}\verb+}+.\ixcom{reference}
+
+\begin{example}
+The \latex{} source for the bibliography in one version of this document was:
+\begin{verbatim}
+\infannex{Bibliography}
+\begin{references}
+\reference{LAMPORT, L.,}{\latex\/ A Document Preparation System,}%
+           {Addison-Wesley Publishing Co., 1986} \label{lamport}
+\reference{GOOSSENS, M., MITTELBACH, F. and SAMARIN, A.,}{%
+           The \latex\/ Companion,}
+           Addison-Wesley Publishing Co., 1994} \label{goosens}
+\reference{CHEN, P. and HARRISON, M.A.,}{Index preparation and
+           processing,}{Software--Practice and Experience, 19(9):897--915,
+           September 1988.} \label{chen}
+....
+\end{references}
+
+\end{verbatim}
+\end{example} % end example
+
+    Informative references may be cited in the text via the \latex{}
+\verb|\label|\ixcom{label} and \verb|\ref|\ixcom{ref}
+mechanism. Note that \verb|\cite|\ixcom{cite} is not available
+for references to bibliographic items. For the purposes of
+ISO documents, the command 
+\verb+\bref{+\meta{ref}\verb+}+\ixcom{bref}
+is supplied which
+properly formats a bibliographic reference.
+
+\ssclause{Listing of scope items}
+
+    The \verb|inscope|\ixenv{inscope} and 
+\verb|outofscope|\ixenv{outofscope}
+environments are provided for itemized listing of elements that
+are within and outside the scope of the standard. Each list
+element is introduced via the \verb|\item|\ixcom{item} command. 
+Some boilerplate
+text is also printed that introduces the scope list.
+
+    The environments take one parameter, \meta{text}, that must read
+naturally in a sentence of the form: `The following are within/outside
+the scope of this \meta{text}:'. The non-parameterized part of this
+sentence is specified by the commands 
+|\verb|\inscopename|\ixcom{inscopename} and
+\verb|\outofscopename|\ixcom{outofscopename}
+ respectively for `within' and `outside'.
+
+\begin{example}The following text was printed by the commands shown at the
+end of the example.
+
+\begin{inscope}{part of ISO~10303}
+\item use of \latex{} for preparing ISO standard documents;
+\item use of \latex{} for preparing ISO~10303 documents.
+\end{inscope}

+\end{example} % end example
+
+\ssclause{Listing of definitions}
+
+    The \verb|\begin{olddefinitions}| \ldots \verb|\end{olddefinitions}|
+\ixenv{olddefinitions} environment is provided for 
+listing terms that have been defined within
+the normatively referenced documents. Each term in the list is specified as: \\
+\verb+\olddefinition{+\meta{phrase}\verb+}{+\meta{supplement}\verb+}+\ixcom{olddefinition}.
+
+
+    The \verb|\begin{definitions}| \ldots \verb|\end{definitions}|
+\ixenv{definitions} environment is provided for listing 
+the definitions of terms specific to the
+document being written. Each term in the
+list is specified as: \ixcom{definition} \\
+\verb+\definition{+\meta{phrase}\verb+}{+\meta{definition text}\verb+}+.
+
+
+\begin{example}A listing of terms defined elsewhere could be specified as:
+
+\begin{verbatim}
+\begin{olddefinitions}
+\olddefinition{application protocol (AP)}{}
+\olddefinition{integrated resource}{}
+\end{olddefinitions}
+\end{verbatim}
+\end{example} % end example
+\begin{example}The definition listing earlier in this document was produced by:
+
+\begin{verbatim}
+\begin{definitions}
+\definition{boilerplate}{text whose wording is fixed ...}
+\definition{style file}{a set of \latex{} macros assembled 
+                        into a single file}
+...
+\end{definitions}
+\end{verbatim}
+\end{example} % end example
+
+
+\ssclause{Listing of abbreviations}
+
+    The \verb|\begin{symbols}| \ldots \verb|\end{symbols}|\ixenv{symbols}
+environment is provided for listing symbols
+and abbreviations. Each term (either symbol or abbreviation) in the list is
+specified as: \ixcom{symboldef} \\
+ \verb+\symboldef{+\meta{symbol}\verb+}{+\meta{definition text}\verb+}+.
+
+\begin{example}The list of abbreviations earlier in this document was specified as:
+\begin{verbatim}
+\begin{symbols}
+\symboldef{DIS}{Draft International Standard}
+\symboldef{IS}{International Standard}
+...
+\end{symbols}
+\end{verbatim}
+\end{example} % end example
+
+\sclause{Floating bodies}
+
+    \latex{} provides the \verb|figure|\ixenv{figure}
+and \verb|table|\ixenv{table} environments.
+Captions (produced by the \verb|\caption|\ixcom{caption}
+command) increment the figure or
+table number and add the caption to the relevant contents listing file.
+
+\index{floats} \index{floats!continuation}
+
+    The command 
+\verb+\contcaption{+\meta{text}\verb+}+\ixcom{contcaption}
+may be used instead. This command neither increments the number nor adds
+anything to the listing files.
+
+\begin{example}
+The following code:
+\begin{verbatim}
+\begin{table}[tbp]

+\sclause{Title command}
+
+
+    The command to produce the title of the standard\ixcom{title}
+is 
+\verb+\title{+\meta{intro}\verb+}{+\meta{main}\verb+}{+\meta{compl}\verb+}+. 
+The command takes three parameters
+according to the three elements of the title as specified in the ISO directives.
+\begin{enumerate}
+\item \meta{intro} The introductory element of the title. This may be empty.
+\item \meta{main} The main element of the title.
+\item \meta{compl} The complementary element of the title. This may be empty.
+\end{enumerate}
+
+\begin{example}
+If this were actually meant to be an ISO standard, then the \latex{} source 
+for the title of this document might be:
+\begin{verbatim}
+\title{Industrial automation systems and integration}%
+{Product data representation and exchange}%
+{Part 3456 : Documentation methods: The LaTeX style
+file reference manual}
+\end{verbatim}
+\end{example} % end example
+
+\begin{anote}There must be a space on either side of the colon separating the
+part number and the final part of the title.
+\end{anote}% end of note
+
+    Three other commands are used for setting the running header throughout the
+document. These shall be placed in the preamble.\index{preamble}
+
+    The command \verb+\standard{+\meta{number of standard}\verb+}+ is used to identify
+the standard.\ixcom{standard}
+
+    The command \verb+\yearofedition{+\meta{year}\verb+}+ is used to identify the
+\ixcom{yearofedition} year of the edition.
+
+    The command 
+\verb+\languageofedition{+\meta{code}\verb+}+\ixcom{languageofedition}
+ is used to identify the language of the edition.
+
+\begin{example}
+This document is identified by:
+\begin{verbatim}
+\standard{LaTeX for standards}
+\yearofedition{1997}
+\languageofedition{(E)}
+\end{verbatim}
+\end{example} % end of example
+
+    As a convenience the vacuous command \verb+\extrahead+\ixcom{extrahead}
+is supplied which will add it's contents, if any, to the header. It may
+be used, for example, to add a document number to the header by
+\verb+\renewcommand{\extrahead}{Doc number}+. If \verb+\extrahead+ is
+modified it must be done in the preamble.
+
+    The \verb|\title|\ixcom{title} command sets the page numbering 
+style to be arabic,
+starts a new page, numbered 1, and puts the title
+at the start of the page. It also puts the appropriate header at the top
+of the page, dependending on the particular combination of selected
+options.
+
+\begin{anote}
+Remember that you have to use the \verb|copyright|\ixopt{copyright}
+option to enable printing of copyright symbols and notices.
+\end{anote}
+
+\ssclause{The cover}
+
+    For publication, ISO want to be supplied with a document starting
+on page iii with the ToC. They supply the cover (page i) and page ii.
+
+It can often be useful to have a cover page for documents while they
+are in the process of being prepared for submittal to ISO.
+    The \verb+cover+\ixenv{cover} environment is provided for that
+purpose. The contents of the environment must not exceed one page and the
+contents must have a \verb+\clearpage+\ixcom{clearpage} immediately before
+the end. The \verb+cover+ environment also prints page ii, which has a 
+copyright notice on it if the document is copyrighted.
+
+    For example, this document starts with:
+\begin{verbatim}
+\begin{cover}
+\vspace*{4in}
+\begin{center}
+\Huge\bfseries LaTeX for standards
+\end{center}
+\begin{center}
+\bfseries 2001/07/06
+\end{center}
+\begin{center}
+Peter Wilson \\
+\texttt{peter.r.wilson@boeing.com}
+\end{center}
+\clearpage
+\end{cover}
+\end{verbatim}
+
+\sclause{Cross referencing commands}
+
+    The usual \latex{} \verb+\label+\ixcom{label} and
+\verb+\ref+\ixcom{ref} commands are supported. The class also
+provides some formatted referencing commands in addition to \verb+\ref+.
+
+    The following commands are useful for referring to figures, clauses etc.
+Each takes a parameter that is the parameter of a \latex{} \verb|\label{}|
+command.
+
+\begin{itemize}
+\item The command \verb|`\aref{anx:lord}'|\ixcom{aref} prints `\aref{anx:lord}'

+\sclause{Heading commands}
+
+\ssclause{Foreword}
+
+    The \verb|foreword|\ixenv{foreword} environment specifies
+that a table of contents, list of
+figures and list of tables be produced, and starts a new unnumbered
+clause called Foreword.
+Formatting is one column style only and roman page numbering is set. The 
+table of contents starts on page iii.
+
+    More precisely, the title of the clause is given by the value of
+\verb|\forewordname|\ixcom{forewordname} (see \aref{anx:extraiso}).
+
+\begin{note}
+The default style only lists level 1 clauses in the table of contents. If you
+need a more detailed listing, then put the command 
+\verb|\setcounter{tocdepth}{<level #>}|\ixcom{setcounter}\ixtt{tocdepth}
+in the preamble.\index{preamble}
+For example \verb|\setcounter{tocdepth}{3}| will produce a contents
+listing down to the level of \verb|\ssclause| (see \tref{tab:sec} for
+the definitions of clause levels).
+\end{note} %end note
+
+    The command \verb+\fwdbp+\ixcom{fwdbp} prints the 
+ISO specified boilerplate for
+the initial paragraphs of a foreword.
+
+    The boilerplate for a Technical Specification (ISO/TS) or a 
+Publicly Available Specification (ISO/PAS) differs from that
+for a standard. The command \verb|\tspasfwdbp|\ixcom{tspasfwdbp}
+prints some of this boilerplate.
+\begin{example}
+In this document, \verb|\tspasfwdbp| prints:
+
+\tspasfwdbp
+\end{example}
+\begin{note}
+    The required paragraph immediately following this boilerplate is:
+
+ISO/PAS [or ISO/TS] \ldots was prepared by Technical Committee ISO/TC \ldots
+\end{note}
+
+%%    The boilerplate for a Technical Report (TR) also differs from that for
+%%a standard.
+%%The command \verb|\trfwdbpi|\ixcom{trfwdbpi}
+%%prints some of this boilerplate. 
+%%\begin{example}
+%%In this document, \verb|\trfwdbpi| prints:
+%%
+%%\trfwdbpi
+%%\end{example}
+
+    The \verb|\fwdnopatents|\ixcom{fwdnopatents}

+\ssclause{Introduction}
+
+    The \verb|introduction|\ixenv{introduction} environment 
+starts a new unnumbered clause 
+called `Introduction' with one column formatting.
+
+    More precisely, the title of the clause is given by the value of
+\verb|\introductionname|\ixcom{introductionname} (see \aref{anx:extraiso}).
+
+    The \verb|\intropatents|\ixcom{intropatents} prints some of the

+In this document, \verb|\intropatents| prints:
+\fwdnopatents 
+\end{anexample}
+
+
+\ssclause{Scope clause}
+
+    The \verb|\scopeclause|\ixcom{scopeclause} 
+command starts a new numbered clause called `Scope', which is given
+the label \verb|;i1|\index{;i1}.
+
+    More precisely, the title of the clause is given by the value of
+\verb|\scopename|\ixcom{scopename} (see \aref{anx:extraiso}).
+
+\ssclause{Normative references clause}
+
+    The \verb|\normrefsclause|\ixcom{normrefsclause}
+command starts a new numbered clause called `Normative references',
+which is given the label \verb|;i2|\index{;i2}.
+
+    More precisely, the title of the clause is given by the value of
+\verb|\normrefsname|\ixcom{normrefsname} (see \aref{anx:extraiso}).
+
+    The command 
+\verb+\normrefbp{+\meta{document identifier}\verb+}+\ixcom{normrefbp} 
+prints the
+ISO required text for the introduction to the listing of normative
+references. The \meta{document identifier} parameter must be such
+that it reads sensibly in a sentence of the form `\ldots constitute
+provisions of this \meta{document identifier}.'.

+
+\sclause{PDF}
+
+    The class provides a command, \verb|\ifpdf|\ixcom{ifpdf}, 
+to test whether or not the document is being processed by \latex{} 
+or by pdf\latex. \latex{} processing produces a \file{.dvi} file which
+needs further processing, usually by \file{dvips}, to generate PostScript
+for printing. pdf\latex, however, directly generates a \file{.pdf} file
+which can then be printed.
+
+\begin{anexample}
+A document for processing by either \latex{} or pdf\latex{} could be 
+started like:
+\begin{verbatim}
+\documentclass{iso}
+\usepackage{times}
+\ifpdf
+  \pdfoutput=1
+  \usepackage[pdftex]{graphicx}
+\else
+  \usepackage{graphicx}
+\fi
+....
+\end{verbatim}
+
+The \file{times} package is used in this example as PDF printers tend
+to handle
+PostScript fonts better than other kinds of fonts.
+\end{anexample}
+
+
+    The class also supports the use of the 
+\file{hyperref}\ixpack{hyperref} package in conjunction with pdf\latex.
+Typically bookmark processing would be specifed by:
+\begin{verbatim}
+\ifpdf
+  \pdfoutput=1
+  \usepackage[plainpages=false,
+              pdfpagelabels,
+              bookmarksnumbered,
+              hyperindex=true
+             ]{hyperref}
+  ...
+\else
+  ...
+\fi
+....
+\end{verbatim}
+If the \verb|hyperindex=true| option to the \file{hyperref} package is used
+the the index has to be processed via the
+\textsc{MakeIndex}\index{makeIndex@{\sc MakeIndex}} program.

+\clause{The \file{isorot} package facility} 
+
+   The \file{isorot}\ixpack{isorot} facility enables the rotation 
+of document elements on
+a page. It uses the \latex{} \verb|\special|\ixcom{special} 
+command to perform its
+effects, and thus can only be used
+with a limited number of dvi to postscript programs. The facilities
+available are summarized in \tref{tab4}.
+
+    \file{isorot} is a modification of the \file{rotation.sty} file
+created by Rahtz and Barroca~\bref{rahtz}. Further examples of the usage
+of their style are given in Goosens \emph{et al}~\bref{goosens}.
+
+\begin{note}Several examples of the effects of the commands described herein
+are shown. In many cases the results are not pretty. This should act as
+a warning that using rotational elements requires more care than
+most other document elements.\end{note} %end note

+\sclause{Rotational directions}
+
+    \file{isorot} enables the textual and other elements of a document
+to be rotated from their normal horizontal layout. In some cases elements
+can be rotated through arbitrary angles, whereas in others only 90 degree
+rotation is possible. 
+
+    By default, a rotation through a positive number of
+degrees corresponds to a clockwise rotation. The command 
+\verb|\counterclockwise|\ixcom{counterclockwise}
+sets the following rotations to be counterclockwise for positive angles.
+The command \verb|\clockwise|\ixcom{clockwise}
+sets the following rotations to be clockwise for positive angles.
+These commands can be used to toggle the rotational behavior.
+    
+
+    Rotated floating environments are normally rotated so that they are
+printed with a counterclockwise rotation (i.e. the original bottom of the float
+is placed at the right hand side of the paper), 
+which is what is normally required.
+This behavior can be altered by the command
+\verb|\figuresleft|,\ixcom{figuresleft}
+which will give the reverse effect. The command
+\verb|\figuresright|\ixcom{figuresright}
+will set the behavior to the default.
+These commands can be used to toggle the rotational behavior of
+floats.
+
+
+\sclause{Rotation of text}
+
+    The \verb|sideways|\ixenv{sideways}
+environment rotates the contents of the environment
+by 90 degrees counterclockwise, and leaves space for the result.
+
+    The \verb|\begin{turn}{|\meta{angle}\verb|}|\ixenv{turn}
+environment rotates the contents by the given number
+of degrees in the direction specified by the most recent of the
+\verb|\clockwise|\ixcom{clockwise} or
+\verb|\counterclockwise|\ixcom{counterclockwise}
+commands, leaving space for the result.
+
+    The \verb|\begin{rotate}{|\meta{angle}\verb|}|\ixenv{rotate}
+environment rotates the contents by the given number
+of degrees in the direction specified by the most recent of the
+\verb|\clockwise|\ixcom{clockwise} or
+\verb|\counterclockwise|\ixcom{counterclockwise}
+commands, but no arrangements are made for leaving space for the result.
+
+
+\begin{example}Some simple rotations: \label{ex:1}
+
+This code
+\begin{verbatim}
+Default rotation direction: \\
+A 
+\begin{sideways}%
+B C
+\end{sideways}
+D E F G H I J K L M
+\begin{turn}{-90}%
+Minus 90 turn
+\end{turn}
+N O P
+\begin{rotate}{90}%
+Plus 90 rotate
+\end{rotate}
+Q \\
+and continue on with another line after rotations.
+\end{verbatim}
+produces the following (note how space is allowed for the \verb|turn|ed 
+text, whereas the \verb|rotate|d text runs into the text below).
+
+Default rotation direction: \\
+A 
+\begin{sideways}%
+B C
+\end{sideways}
+D E F G H I J K L M
+\begin{turn}{-90}%
+Minus 90 turn

+\sclause{Rotations of tables and figures}
+
+    The previous examples have demonstrated the rotation of textual elements.
+For instance, example~\ref{ex:sidetabular} shows that tabular material can be rotated using
+the \verb|sideways|\ixenv{sideways}
+environment. (Actually, any of the previously
+mentioned environments may be used.)
+Two further environments are provided which rotate a \latex{} float through
+90 degrees. These are:
+\begin{itemize}
+\item \verb|sidewaystable|\ixenv{sidewaystable}, which
+  corresponds to the standard \latex{} \verb|table|\ixenv{table}
+  environment; and
+\item \verb|sidewaysfigure|\ixenv{sidewaysfigure}, which
+  corresponds to the standard \latex{} \verb|figure|\ixenv{figure}
+  environment.
+\end{itemize}
+There are also starred versions of these, namely 
+\verb|sidewaystable*|\ixenvs{sidewaystable} and
+\verb|sidewaysfigure*|\ixenvs{sidewaysfigure}, for use in twocolumn mode.
+However, the correspondence with the standard environments is not strictly
+complete as a sideways float is alway placed on a page by itself.
+
+    The direction of rotation may be controlled by the 
+\verb|\figuresright|\ixcom{figuresright} and
+\verb|\figuresleft|\ixcom{figuresleft} commands.
+
+\begin{example}Table~\ref{tab4} is produced by the code below: \label{ex:4}

+
+\sclause{Rotation of float captions and bodies}
+
+    Sometimes it may be useful to rotate a caption independently of the
+rotation of a figure or table. The command 
+\verb|\rotcaption|\ixcom{rotcaption} is analogous
+to the normal \verb|\caption|\ixcom{caption} command, 
+and inserts the caption rotated
+by 90~degrees. There is also the companion command 
+\verb|\controtcaption|\ixcom{controtcaption}, analagous to the
+\verb|\contcaption|\ixcom{contcaption} command,
+for continuation captions.

+
+    \latex{} normally prints in portrait mode. 
+The \verb|landscape|\ixenv{landscape} environment

+and footers which are not rotated.
+
+\begin{example} Landscaping
+
+The source for this part of the document is:
+\begin{verbatim}
+\begin{landscape}
+\sclause{Landscaping}
+
+    \latex{} normally prints in portrait mode. The ...
+...
+... long, wide tables.
+\end{landscape}
+\end{verbatim}
+\end{example}
+
+    The environment starts by clearing the current page and then switches
+to portrait mode. At the end of the environment the current page is cleared
+and the next page is back to normal portrait mode. 
+
+    All the other rotation commands and environments produce boxes and
+\latex{} will not break a box across a page. The \verb|landscape| environemt
+does not produce a box and so many pages can be printed in landscape mode
+with \latex{} taking care of the page breaking for you. 
+
+    Landscape mode is not particularly useful for normal text as the
+lines are far too long for comfortable reading. Where it can be useful
+is where you have a table that is too wide to fit on a portrait page, so
+needs to be rotated, yet is also too long to fit on the page when it is
+rotated. The \file{supertabular}\ixpack{supertabular},
+the \file{longtable}\ixpack{longtable},
+and the \file{xtab}\ixpack{xtab}
+packages provide facilities for automatically breaking long tables across 
+pages. Any of these can be used in conjunction with landscaping to both 
+rotate and automatically page break long, wide tables.

+                         You supply the specification of the columns
+                         just as for the normal tabular environment.
+                         All commands that can be used within a tabular
+                         environment can also be used within
+                         the xtabular environment.
+ \\
+ &
+    Unlike the tabular environment which prevents page breaking
+within the tabular, the xtabular allows page breaking, so that
+tabulars can extend automatically across several pages. Xtabular
+starts off with a tabular environment and checks the amount of
+space left on the page as it adds each row to the tabular.
+If the space left on the page is too short for another row, then
+it ends the current tabular, performs a page break and starts
+another tabular on the following page. This process is repeated
+until all the rows have been output. 
+ \\
+ &
+    There are special commands for captioning a xtabular as a
+table, and also elements can be automatically inserted after each
+(internal) \verb|\begin{tabular}| and immediately before each
+\verb|\end{tabular}|.
+ \\
+ &
+    Do not put a xtabular in a table environment, as the table
+environment keeps its contents on a single page (presumably you
+are using xtabular because its contents are longer than
+one page).
+ \\
+\verb|\end{xtabular}| & End the xtabular environment. \\ \hline
+\verb|\begin{mpxtabular}| & Like the xtabular environment
+except that each `page' is put into a \verb|minipage| first. Thus
+it is possible to have footnotes inside an \verb|mpxtabular|.
+The footnote text is printed at the end of each page.
+ \\
+\verb|\end{mpxtabular}| & End the mpxtabular environment. \\ \hline
+                          & \textbf{Note:} If any of the following commands
+                            are used, then they should be placed
+                            before the particular xtabular
+                            environment that they apply to. \\
+\verb|\topcaption{...}| & A command to provide a caption for the
+                          table. The caption is placed at the top
+                          of the table. \\
+\verb|\bottomcaption{...}| & A command to provide a caption for the
+                          table. The caption is placed at the bottom
+                          of the table. \\
+\verb|\tablecaption{...}| & A command to provide a caption for the
+                          table. The caption is placed at the default
+                          position, which is at the top
+                          of the table.
+ \\
+ & 
+                           \textbf{Notes:} You cannot use the \verb|caption|
+                            command but you can put a label after
+                            any of these captioning commands. If you
+                            want captioning, the command must be specified
+                            before the start of the xtabular environment.
+  \\
+  &
+                            The \verb|\...caption{}| command(s) remain
+                            in effect until changed by another
+                            \verb|\...caption| command.
+   \\
+\verb|\tablefirsthead{...}| & Defines the contents of the first occurence
+                         of the tabular head. The tabular head is some
+                         special treatment of the first row in the table.
+                         This command is optional.
+                         If used, the header must be closed by the
+                         end of line command for tabulars (e.g., \verb|\\|). \\
+\verb|\tablehead{...}| & Defines the contents of the table head on
+                         subsequent pages.
+ \\
+ &
+                         For example, you might want to note that
+                         this is a continuation of the table on
+                         the previous page, as well as repeating
+                         any column headings that were given
+                         at the start of the xtabular by
+                         \verb|\tablefirsthead|.
+ \\
+\verb|\tablelasthead{...}| & Defines the contents of the table head
+                            on the last page of the table.
+ \\
+ &
+    This works by writing to the \file{.aux} file the number of
+pages that the xtabular extends over. When the xtabular
+comes to the last tabular (which it calculates from the 
+information it reads from the \file{.aux} file) it replaces the
+contents of \verb|\tablehead| by the contents of \verb|\tablelasthead|.
+ \\
+ &
+It makes no attempt to measure the amount of space used by the last
+table head, so if this is more than for \verb|tablehead| then the
+tabular might be a litle too long.
+  \\

+\end{xtabular}
+\end{center}
+\end{verbatim}
+\end{example}       
+
+    The table is only broken between rows --- a row will not be split
+across pages. This can lead to some bad page breaks, especially if 
+there are rows with a large vertical height (like some in \tref{tab:xtab}).
+It is best to keep rows not too tall.
+
+The command
+\verb|\shrinkheight{|\meta{length}\verb|}|\ixcom{shrinkheight} may be
+used after the first \verb|\\| in the table to modify the allowed
+height of the table on each page. A positive \meta{length} decreases
+the allowed space per page and a negative \meta{length} increases
+the allowed space.
+
+\begin{example}
+This example illustrates changing the natural height of the pages
+in a \verb|xtabular| and its relatives.
+
+\verb|\shrinkheight{2\baselineskip}| decreases the space per page by 
+two lines.
+
+\verb|\shrinkheight{-\baselineskip}| increases the space per page by
+one line.
+\end{example}
+
+    You have to specify the font used for the 
+\verb|\tablehead|\ixcom{tablehead} and
+\verb|tablelasthead|\ixcom{tablelasthead} yourself. 
+Within ISO documents, captions shall
+be in bold font. The \file{iso}\ixclass{iso} class also provides 
+a command for
+setting the size of the font used in captions, namely 
+\verb|\captionsize|\ixcom{captionsize}. 
+Note that this is used in~\eref{ex:xtab}.
+    The value of \verb|\captionsize|\ixcom{captionsize} is set by the 
+class.
+
+\sclause{Options}
+
+    The \file{xtab} package has three options which control the amount of
+information that is written to the \file{.log}\index{file!.log} file. The
+options are:
+\begin{enumerate}
+\item The option \verb|errorshow|\ixopt{errorshow} (the default) does not
+      write any extra information;
+\item The option \verb|pageshow|\ixopt{pageshow} writes information
+      about when and why \verb|xtabular| decides to produce a new page;
+\item The option \verb|debugshow|\ixopt{debugshow}, which also includes
+      \verb|pageshow|, additionally writes information about each line
+      that is added to the table.
+\end{enumerate}
+
+    Under normal circumstances \file{xtab} is used without invoking any 
+option. The \verb|pageshow| option may be useful when attempting to cure
+a bad page break. The \verb|debugshow| option, as its name implies, is
+principally of use to the \file{xtab} developer.
+
+    Independently of the options, the command 
+\verb|\sstraceon|\ixcom{sstraceon} may be used at any
+point in the document to turn on printing of \verb|debugshow| data. This
+can be turned off later by the \verb|\sstraceoff|\ixcom{sstraceoff}
+command, which will stop all \verb|...show| printing.
+
+\sclause{Caveats}
+
+    The authors of the original \file{supertabular} package note that
+it has the following weaknesses:
+\begin{itemize}
+\item Sometimes the body of the first page of a table gets moved to the 
+following, leaving the caption behind;
+\item Sometimes the last page of a table consists of just the head and foot
+with no contents.
+\end{itemize}
+The weaknesses are caused by trying to guess where \tex{} will put a page 
+break. The package has to guesstimate how long the next entry will be in 
+the table and, if it is too long for the available space, it puts in its
+own page break. If its guess is off too much in one direction, \tex{} will 
+break the page unexpectadly; if its off in the other direction
+\file{supertabular} will put in an unnecessary page break.
+
+    The \file{xtab} package has reduced, but perhaps not entirely
+eliminated, these weaknesses. Some hand tuning may still be required.

+\clause{The \file{askinc} package facility} 
+
+    The \file{askinc}\ixpack{askinc} package facility contains \latex{} 
+code to enable the interactive
+input of files. This functionality is a cross between the \latex{}
+\verb|\include|\ixcom{include} and 
+\verb|\includeonly|\ixcom{includeonly} commands, and the
+\verb|\input|\ixcom{input} command.
+
+In the body of the root source document, use the command 
+\verb+\infile{+\meta{file}\verb+}+\ixcom{infile}
+for each \meta{file}
+that comprises the document. That is, the command \verb|\infile| is similar
+to the \verb|\input|\ixcom{input} and
+\verb|\include|\ixcom{include} commands.
+
+    When \latex ing the root document, you will be asked to provide a 
+comma-separated list of the \verb|\infile|s to be processed (similar to the
+argument to the \verb|\includeonly|\ixcom{includeonly}
+command). If you want all the files to be processed, just hit the
+\verb|<RETURN>| key (or its equivalent).
+
+    Like \verb|\include|d files, a file that is \verb|\infile|d into a

+\clause{The \file{hyphenat} package facility} \label{sec:uschyp}
+
+    The \file{hyphenat} package is fully described in~\bref{bib:hyphenat}.
+This clause provides an overview of the portions of the package that are
+most relevant to typesetting ISO standards.
+
+    In \latex{} if you need to use the underscore (\verb|_|)
+character in normal text, for example when documenting identifiers
+in a programming language code, you have to use the 
+\verb|\_|\index{_ /@\verb?\_?} command,
+as in \verb|a\_multiword\_identifier|. \latex{} normally treats
+\verb|_|\index{_@\verb?_? (underscore)} as a math mode subscript command. 
+Further, if you want
+the possibility of hyphenation\index{hyphenation} 
+at the position of an underscore
+you have to use the command pairing 
+\verb|\_\-|;\index{_ /@\verb?\_?}\ixcom{-} this has the side
+effect of disabling normal hyphenation in any succeeding `word' in
+the identifier.
+
+    The \file{hyphenat}\ixpack{hyphenat} package facility redefines the 
+\verb|\_|\index{_ /@\verb?\_?} command
+so that hyphenationen is automatically enabled at the position
+of the underscore and in all succeeding words in the identifier.
+
+
+\begin{note}
+    Using the command pair \verb|\_\-| in conjunction with this facility
+disables automatic hyphenation of succeeding words, so don't do it.
+\end{note}
+
+
+
+\begin{example} \label{eg:uschyp}

+\end{itemize}
+\end{minipage}
+
+\end{example}
+
+
+    The \file{hyphenat} package also provides some other commands for
+enabling hyphenation of words that include 
+analphabetic\index{character!analphabetic}\footnote{An {\it analphabetic} 
+character is any character
+that is not alphabetic. Typically it refers to punctuation characters.}
+characters. In this context, the phrase 
+`breakable character'\index{character!breakable} is used
+to describe an analphabetic character that enables hyphenation immediately
+after it and does not prevent further hyphenation in the `word'
+in which it occurs. The \verb|\_|\index{_ /@\verb?\_?} command produces 
+a breakable underscore. Table~\ref{tab:breakable} lists all the commands
+that generate breakable characters.
+
+\begin{table}
+\centering
+\caption{Commands producing breakable characters} \label{tab:breakable}
+\begin{tabular}{|l|c|} \hline
+\textbf{Command}    & \textbf{Character} \\ \hline
+\verb|\_|        & \_ \\

+\verb|\bshyp|    & \bshyp \\
+\verb|\colonhyp| & \colonhyp \\
+\verb|\dothyp|   & \dothyp \\
+\verb|\fshyp|    & \fshyp \\ \hline
+\end{tabular}
+\end{table}
+
+    The \verb|\bshyp|\ixcom{bshyp} command prodes a breakable backslash
+(\verb|\|), \verb|\fshyp|\ixcom{fshp} produces a breakable forward
+slash (\verb|/|), the \verb|\dothyp|\ixcom{dothyp} command produces a
+breakable full stop (\verb|.|), also known in some countries as a period,
+and the \verb|\colonhyp|\ixcom{colonhyp} command produces a breakable 
+colon (:).
+
+\begin{example}
+This is similar to \eref{eg:uschyp} except that it demonstrates other
+breakable characters.
+
+This set of \latex{} source

+\fshyp{}demonstrating\dothyp{}hyphenation
+\end{minipage}
+
+\end{example}
+
+\begin{note}
+\latex{} will not hyphenate the first word in a paragraph.
+\end{note}
+
+    Just as with the \verb|\_|\index{_ /@\verb?\_?} command, 
+the discretionary hyphen
+command (i.e., \verb|\-|\ixcom{-}) should not be used in conjunction with 
+any of the breakable character commands as it will then inhibit any
+further potential hyphenation points. In general, any analphabetic
+character in a word will inhibit further hyphenation.
+

+\sclause{Caption text size}
+
+    The size of the font used for typestting the captions of figures and
+tables is defined within the \file{iso}\ixclass{iso} class.
+% The
+%\verb|uglycaption|\ixopt{uglycaption} option resets the size to larger
+%than normal for the captioning text.
+
+    The size of the captioning font is controlled by the value of the
+\verb|\captionsize|\ixcom{captionsize} command. The default definition
+of \verb|\captionsize| is similar to:
+\verb|\captionsize{\normalsize}| \ixcom{normalsize}\\
+%The \verb|uglycaption| option resets this to (approximately): \\
+%\verb|\captionsize{\large}|. \ixcom{large}
+
+    You can reset the \verb|\captionsize| at any point in your
+document to change the size of captions from then onwards.
+
+    All the normal \latex{} font size commands are available.
+\begin{example}
+The following shows the effects of the font size commands. \\

+\infannex{Creating an index} \label{anx:indexing}
+
+    \latex, although providing some assistance in preparing the data for an
+index\index{index}, only does part of the job. Providing the command
+\verb|\makeindex|\ixcom{makeindex} is put in the document's 
+preamble\index{preamble}
+the \latex{} command \verb|\index{text}|\ixcom{index} 
+writes out \verb|text| to an \file{.idx}\index{file!.idx} file 
+in the following format:\ixcom{indexentry}
+\begin{verbatim}
+\indexentry{text}{pg}
+\end{verbatim}
+where \verb|pg| is the page number in the document where the \verb|\index|
+command occurred.
+
+    The \verb|theindex|\ixenv{theindex} environment 
+is used for printing an index. The format of this is:
+\begin{verbatim}
+\begin{theindex}
+\item <text and page numbers>
+  \subitem <text and page numbers>
+    \subsubitem <text and page numbers>
+.
+.
+\end{theindex}
+\end{verbatim}
+where \verb|\item|\ixcom{item} is a major topic entry,
+\verb|\subitem|\ixcom{subitem} is a sub-topic entry, and
+\verb|\subsubitem|\ixcom{subsubitem} is a sub-subtopic
+entry. The command \verb|\indexspace|\ixcom{indexspace}
+can be used to add space between the entries. Other text and commands can also
+occur within the environment.
+
+    \latex{} provides no help in going from an \file{.idx} file to the
+\verb|theindex| environment~\bref{lamport}. The data in the file has to be
+sorted, duplicate page numbers deleted, etc, and then re-written in the 
+desired environment format.
+
+    The typical process for producing a document with an index is:
+\begin{enumerate}
+\item Prepare the source file, say \file{fred.tex}, with the command
+      \verb|\makeindex|\ixcom{makeindex} in the
+      preamble\index{preamble}, and \verb|\index|\ixcom{index}
+      commands within the body of the text.
+\item Run \latex. As well as producing the usual output files, it will also
+      produce the file \file{fred.idx}.
+\item By some means produce a file, let's call it \file{fredidx.tex}, from the 
+      data in \file{fred.idx} that contains the appropriate \verb|theindex|
+      formatted data.
+\item Run \latex{} again on \file{fred.tex} which now has to contain (either
+      via \verb|\input|\ixcom{input} or \verb|\include|\ixcom{include})
+      the file \file{fredidx.tex}.
+\end{enumerate}
+
+    Chen and Harrison~\bref{chen} discuss the problems of creating an index 
+in their
+paper \emph{Index preparation and processing} and also describe the
+{\sc MakeIndex}\index{makeIndex@{\sc MakeIndex}} program. Goosens, Mittelbach
+and Samarin~\bref{goosens} also describe how to use the {\sc MakeIndex} 
+program for producing indexes for \latex{} documents. For users of
+{\sc MakeIndex} a style file called 
+\file{iso.ist}\index{iso.ist@\file{iso.ist}}\index{file!.ist} is provided as
+part of this distribution.
+
+\sclause{The index command}\ixcom{index}
+
+    The \verb|\index| command is one of the standard \latex{} commands.
+The command format is \verb|\index{|\meta{str}\verb|}|, where \meta{str}
+ is any
+string of characters, and it writes an entry to the \file{.idx} file in
+the form \verb|\indexentry{<str>}{pg}|, where \verb|pg| is the page
+number in the document where the command is called.
+
+    Some points to note:
+\begin{itemize}
+\item The \verb|\index| command is, in \latex{} terminology, 
+      \emph{fragile}\index{fragile}. That is, if it appears in a moving
+      argument (like the caption to a table or figure) it must be preceded
+      by the \latex{} \verb|\protect|\ixcom{protect}
+      command.
+\item Any of the ten \latex{} special characters\index{special characters}
+      (i.e., \verb|#|, \verb|$|, \verb|%|, \verb|&|, \verb|~|, \verb|_|,
+             \verb|^|, \verb|\|, \verb|{| and \verb|}|) may appear
+     within the argument, with the proviso that it must have no unmatched
+     braces (the braces in \verb|\{| and \verb|\}| are counted in the
+     matching process).
+\item The \verb|\index| command must not appear inside another command's
+     argument (e.g., within a 
+     \verb|\footnote|\ixcom{footnote} or \verb|\clause|\ixcom{clause}
+     command) unless the argument of the \verb|\index| command contains
+     only letters, digits, and/or punctuation characters. In particular,
+     it should not contain any of the special characters.
+  \begin{note}This means that the argument of the \verb|\ix|\ixcom{ix}
+        command should not contain any special characters. Remember that the
+       \verb|\ix| command prints its argument in the body of the text and also
+       calls \verb|\index| to place its argument into the \file{.idx} file.
+       \end{note} % end note
+\end{itemize}
+
+\begin{note}Under some circumstances, an \verb|\index| command appearing in another
+command's argument may contain special characters, provided they are 
+\verb|\protect|ed. Determination of when this is satisfactory is a process
+of trial and error.
+\end{note} % end note
+
+\begin{example}The command \verb|\ix{an\protect\_underscore}| will print the
+characters \emph{an\_undescore}
+in the text and also write the following to the \file{.idx} file:
+\begin{verbatim}
+\indexentry{an\_ underscore}{pg}
+\end{verbatim}
+Notice that there is a space between the underscore character and the word
+`underscore' in the \file{.idx} file (but there is no space in the printed
+body of the document text). This extraneous space may have to be edited out 
+from the final index.
+\end{example} % end example

+\sclause{The program GenIndex} \index{genindex@GenIndex}
+
+    GenIndex is a C program\index{C language} that converts \file{.idx}
+data to \verb|theindex|\ixenv{theindex} data. 
+Source code for GenIndex is freely available from
+the NIST SOLIS\index{SOLIS} system (see \ref{anx:solis}). 
+The GenIndex program is not
+as sophisticated as {\sc MakeIndex} but does a reasonable 
+job.\footnote{These two programs are not completely compatible but do have
+a common subset of commands. The common subset excludes the {\tt SeeAlso}
+and {\tt See} commands. At some later time GenIndex may be rewritten to
+be compatible with {\sc MakeIndex}. It is probably advisable, therefore, not
+to use the GenIndex {\tt SeeAlso} and {\tt See} commands.}
+
+
+\ssclause{Input} \index{genindex@GenIndex!input}
+
+    GenIndex reads lines of data of the form:
+\begin{verbatim}
+\indexentry{IndexData}{Page}
+\end{verbatim}
+
+    \verb|Page| is a character string representing a page number. GenIndex only
+recognizes strings that represent integer values greater than or equal to zero,
+or (upper and lower case) roman numerals. For any other numbering system, the
+page number is treated as zero.
+
+    \verb|IndexData| is a string of characters and command characters that
+specify the data that is to be indexed. In the simplest case, this is just the
+word or phrase to appear in the index, but much more can be done than this, as
+is described below.
+
+    The general form of \verb|IndexData| is given by the following partial
+grammar:
+\begin{verbatim}
+IndexData  = MainData ['!' SubData ['!' SubSubData ] ] .
+MainData   = Data .
+SubData    = Data .
+SubSubData = Data .
+Data       = Key [ Entry ] [ SeeAlso ] [ See ] .
+Key        = any string not containing the @, !, + or * characters .
+Entry      = '@' any string not containing the !, + or * characters 
+                 (unless enclosed in braces {} ) .
+SeeAlso    = '+' any string not containing the ! or * characters
+                 (unless enclosed in braces {} ) .
+See        = '*' any string not containing the ! character
+                 (unless enclosed in braces {} ) .
+\end{verbatim}
+
+    Upto three levels of indexing are enabled --- a main topic entry, an optional
+sub-topic, and an optional sub-subtopic. The sub-topics for an entry are
+introduced by the \verb|!| character. \index{(33@{\verb?!?}}
+
+     Apart from \verb|Key|, braces within a string must be matched. That is,
+they must appear in pairs of an opening and a closing brace.
+Spaces are significant within the \verb|Key| string, but not in the others.
+That is, \verb*|\indexentry{A}| differs from \verb*|\indexentry{ A}| 
+both of which differ from \verb*|\indexentry{A }|.
+
+
+\begin{example}Here is an index entry for a simple topic:
+\begin{verbatim}
+\indexentry{Topic}{27}
+\end{verbatim}
+\end{example} % end example
+\begin{example}And here is one where the key and the main entry are different, a 
+sub-topic is being indexed, and the page is in roman numerals:
+\begin{verbatim}
+\indexentry{main@\textbf{Main}!sub topic}{xviii}
+\end{verbatim}
+\end{example} % end example
+\begin{example}This is how the characters \verb|@|, \verb|!|, \verb|+| and
+\verb|*| characters are indexed in this document.
+\begin{verbatim}
+\index{(64@{\verb?@?}}
+\index{(33@{\verb?!?}}
+\index{(43@{\verb?+?}}
+\index{(42@{\verb?*?}}
+\end{verbatim}
+\end{example} % end example
+
+
+\sssclause{Key} \index{genindex@GenIndex!input!key}
+
+    The indexed entries are sorted alphabetically on the value of \verb|Key|.
+Sorting is case-insensitive. A \verb|Key| value is required.
+
+    More precisely, the key entries are sorted according to the
+C language\index{C language} implementation collating sequence, which is usually ASCII. 
+Table~\ref{tab:ascii} gives the ASCII collating sequence for the \latex\

+otherwise it writes \verb|\otherindexspace{c}|.
+\end{anote} % end note
+
+\begin{example}
+These commands could be defined as:
+\begin{verbatim}
+\newcommand{\alphaindexspace}[1]{\indexspace
+                       {\bfseries #1}}
+\newcommand{\otherindexspace}[1]{}

+which would result in the printing of a vertical space and a bold font text
+for an alphabetic header, or nothing for anything else.
+\end{example} % end example
+
+\ssclause{Running GenIndex} \index{genindex@GenIndex!run}
+
+    To run GenIndex, first obtain a copy of the program, and compile it if
+necessary. Execute the program on your data.
+
+    GenIndex takes zero, one or two file names as parameters. If no files are
+given then input and output is from and to \verb|stdin| and \verb|stdout|
+respectively.
+
+    If one file is given, then input is taken from this file, and output
+is to \verb|stdout|.
+
+    If two file names are given, then input is taken from the first and output
+is to the second.
+
+\begin{example}
+A typical usage would be:
+\begin{verbatim}
+GenIndex fred.idx fredidx.tex
+\end{verbatim}
+which would read the \file{fred.idx} file and write the resulting index data to
+file \file{fredidx.tex}.

+% 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 ISO~10303 documents 
+using manual methods, which are time consuming and expensive. 
+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{iso} 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
+ISO \latex{} documents into HTML\footnote{Later, configuration files for XML
+output will be developed.}.
+
+    Some 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.
