+% \textbf{Overview of the \RS\ package}
+% \end{center}
+% \noindent
+% When writing complex documents, often a large number of commands
+% for different type of references are defined, for example:
+% \begin{Ipara}
+% |\newcommand*{\eqref}[1]{eqn~(\ref{#1})}|\\
+% |\newcommand*{\Eqref}[1]{Equation~(\ref{#1})}|
+% \end{Ipara}
+% The \RS package was developed to automate this process. The
+% package provides a user interface to define sets of reference
+% and label commands for each referable object such as an equation
+% or a table, etc. When you declare, for example, a set of
+% reference commands to an equation:
+% \begin{Ipara}
+% \cmd{\newref}|{eq}|\mkeylst\
+% \end{Ipara}
+% \noindent
+% a series of commands of the format \cmd{\eq...} and \cmd{\Eq...}
+% are produced. The configuration options are set with a list of
+% key-values. Prefixes, inserts and other options for all the
+% different perturbations such as capitalized first letters,
+% singular and plural from, etc.\ can be defined. The
+% configuration can be changed temporarily with an optional list
+% of key-values when the commands are used. A direct interface to
+% the \pkg{varioref} package is also provided.
+% This enables compact reference formats:
+% \begin{Itabb}
+% \hspace{14em}\=\kill
+% |\eqref{e1} ...| \ArTab\eqref{e1} ...\\
+% |\Eqref[vref]{e1} ...| \ArTab\Eqref[vref]{e1} ...\\
+% |\eqref[s]{e1} and ...| \ArTab\eqref[s]{e1} and ...\\
+% |\eqref[name=eq.~]{e1} ...| \ArTab\eqref[name=eq.~]{e1} ...
+% \end{Itabb}
+% A range or a list of references can also be referred to in a
+% consistent way.
+% \begin{Itabb}
+% \hspace{14em}\=\kill
+% |\eqref{e1,e2,e3} ...| \ArTab\eqref{e1,e2,e3} ...\\
+% |\eqrangeref[vref]{e1}{e3} ...| \ArTab\eqrangeref[vref]{e1}{e3} ...
+% \end{Itabb}
+%
+% Templates for the different reference types and different
+% languages can be loaded with a configuring file.
+%
+% The package is aimed at large projects, enabling a consistent
+% way of producing references throughout a project. Enough
+% flexibility is provided to make local changes to a single
+% reference. For large projects such as a series of books or a
+% multi volume thesis, written as freestanding documents, a
+% facility is provided to interface to the \pkg{xr} package for
+% external document references.

+% \section{Loading the \RS Package}
+%
+% The \RS package is loaded in the preamble of the document:
+% \begin{enumerate}
+% \item[(a)]
+% With a default configuration file \file{refstyle.cfg}.
+% \begin{Ipara}
+% |\usepackage{varioref}[2001/09/04]%|~
+% ${\leftarrow}$ To use the \opt{vref} option\\
+% |\usepackage{refstyle}|
+% \end{Ipara}
+% The default config file provided with this package contains
+% interfaces to \pkg{babel} for language changes.
+% A sample configuration file, \file{reftmpl.cfg}, is provided in
+% \secref{templates}. It can be generated by running
+% \file{refstyle.dtx} through \pkg{docstrip} with the
+% \opt{<tmpl>} option. Modify \file{reftmpl.cfg} according
+% to your requirements and place it in a directory where
+% \TeX\ can find it.
+%
+% \item[(b)]
+% Or with your own configuration file for a specific project:
+% \begin{Itabb}
+% |\usepackage[noconfig]{refstyle}|\\
+% |\input{thisproject.ref}|
+% \end{Itabb}
+%
+% \item[(c)]
+% Or without any configuration file, but by declaring your own
+% reference commands in the preamble.
+% \begin{Itabb}
+% \cmd{\usepackage}|[noconfig]{refstyle}|\\
+% \qquad\cmd{\newref}\marg{reftype$_{\,1}$}\mkeylst \\
+% \qquad\cmd{\newref}\marg{reftype$_{\,2}$}\mkeylst\\
+% \tab$\vdots$
+% \end{Itabb}
+%
+% \end{enumerate}
+%
+%
+% \subsection{Companion packages}
+%
+% The \RS packages is intended for large projects. It is therefore
+% important that it works together with, or has direct interfaces
+% to the following packages:
+% \begin{description}
+% \item[\pkg{varioref}:\footnotemark]
+% \footnotetext{\pkg{varioref} v1.3c, 2001/09/04 or later,
+% because the starred versions of the commands
+% are used.}
+% Produce sophisticated page and page range references.
+%
+% \item[\pkg{hyperref}:\footnotemark]
+% \footnotetext{\pkg{hyperref} v6.72r, 2002/05/27 or later,
+% where a bug for interference with
+% \pkg{varioref} was fixed.}
+% To establish hyper links between the references and the
+% labels.
+%
+% \item[\pkg{xr}:]
+% To establish references to external documents.
+%
+% \item[\pkg{showkeys}:]
+% To show all the labels and references. This is very useful
+% to find labels in large documents.
+% \end{description}
+%
+% \pagebreak
+% \section{User Interface}
+%
+% The \RS package has one configuring command, \DescribeMacro{\newref}
+% \cmd{\newref}, that internally creates a series of label and
+% reference commands:
+% \blankline
+%
+% \begin{cminipage}[\linewidth]
+% \newcommand*{\crsi}{\smash{\rule[0pt]{.4pt}{1.25em}\rule[.5ex]{1.5em}{.4pt}}}^^A
+% \newcommand*{\crsl}{\smash{\rule[.5ex]{.4pt}{1.5em}\rule[.5ex]{1.5em}{.4pt}}}^^A
+% \begin{Itabb}
+% \hspace*{2em}\=\hspace{2em}\=\kill
+% \cmd{\newref}\marg{\rtp}\mkeylst\tab\mbox{}\\[.75ex]
+% \>\crsi \>\argcmd{{\rtp}}{key}\\[.75ex]
+% \>\crsl \>\argcmd{{\rtp}}{label}\\[.75ex]
+% \>\crsl \>\argcmd{{\rtp}}{ref}\\[.75ex]
+% \>\crsl \>\argcmd{{\Rtp}}{ref}\\[.75ex]
+% \>\crsl \>\argcmd{{\rtp}}{rangeref}\\[.75ex]
+% \>\crsl \>\argcmd{{\Rtp}}{rangeref}\\[.75ex]
+% \>\crsl \>\argcmd{{\rtp}}{pageref}
+% \end{Itabb}
+% \end{cminipage}
+% \blankline
+%
+% \noindent
+% All the \cmeta{\rtp}... commands, excluding \argcmd{{\rtp}}{key},
+% are robust.
+% All the options for the referencing commands are set with a
+% key-value list. \Tabref[vref=far]{refopt} gives a full list of all the
+% key-values and defaults.
+%
+% The \RS package do not redefine any internal \LaTeX\ commands and
+% depends only on the \cmd{\label}, \cmd{\ref}, \cmd{\pageref} and
+% the \pkg{varioref} commands.
+% The internally defined commands do not overwrite any
+% existing command with the same name, and an error results if a command
+% already exists. The exception is commands declared with a previous
+% \cmd{\newref} call, can be redefined by calling \cmd{\newref} again
+% with a new set of parameter.
+% If the \pkg{amsmath} package is loaded, and you define
+% \cmd{\newref}|{eq}| for references to equations, you need to
+% undefine \cmd{\eqref} before issuing \cmd{\newref} by
+% \begin{Ipara}
+% \cmd{\let}\cmd{\eqref}|=|\cmd{\relax}
+% \end{Ipara}
+%
+%
+% \section{Command Descriptions}
+%
+% The structure of the label and reference commands is given by the
+% syntax diagrams that follows. Examples are included for references
+% to equations, defined according to the template in
+% \secref{EqTempl} with the
+% \cmd{\newref}|{eq}|\mkeylst. See also \secref{keyvals} for
+% explanations of the key-values.
+%
+% \subsection{The reference key}
+%
+% \begin{cminipage}[\linewidth]
+% \begin{syntdiag}
+% \tok{\argcmd{\rtp}{key}}
+% \end{syntdiag}
+% \end{cminipage}
+% \blankline
+% \noindent
+% The \argcmd{\rtp}{key} command returns the prefix added to the
+% argument of the label and the reference commands, for example:
+%
+% \begin{Itabb}
+% \hspace{10em}\=hspace{5em}\=\kill
+% \cmd{\newref}\marg{\rtp}|{}|
+% \>\>\argcmd{\rtp}{key} $\rightarrow$ \meta{type\,:\,}\\
+% \cmd{\newref}\marg{\rtp}|{key=xxx-}|
+% \>\>\argcmd{\rtp}{key} $\rightarrow$ |xxx-|
+% \end{Itabb}
+%
+% \noindent
+% The \argcmd{\rtp}{key} command is not a general command, but was
+% provided only as a link to the standard \LaTeX{} \cmd{\ref} and
+% \cmd{\pageref} commands:
+%
+% \begin{Itabb}
+% \hspace{10em}\=hspace{5em}\=\kill
+% \cmd{\label}|{|\argcmd{\rtp}{key}| abc}|
+% \>\>~ $\rightarrow$ \cmd{\label}\rmeta{type\,:\,}{abc}\\
+% \cmd{\ref}|{|\argcmd{\rtp}{key}| abc}|
+% \>\>~ $\rightarrow$ \cmd{\ref}\rmeta{type\,:\,}{abc}
+% \end{Itabb}
+% \blankline
+% \noindent
+% \textbf{\slshape Examples:} equations
+% with \cmd{\newref}|{eq}|\mkeylst:
+%
+% \begin{Itabb}
+% \hspace*{18em}\=\kill
+% |\eqkey| \> \eqkey \\
+% |in eq.~\ref{\eqkey e1} ...| \>in eq.~\ref{\eqkey e1} ... \\
+% |on page \pageref{\eqkey e1} ...|\>on page \pageref{\eqkey e1} ... \\

+% \begin{stack}\\ \tok{\okeylst} \end{stack}
+% \tok{"{"<lbl>"}"}
+% \end{syntdiag}
+% \end{cminipage}
+% \blankline
+%
+% \noindent
+% The command \argcmd{\rtp}{label} prefix the reference
+% string in the \cmd{\label} with the string \meta{type\,:\,}, or its
+% redefinition with the \opt{key} option.
+%
+% \begin{Itabb}
+% \hspace{10em}\=hspace{5em}\=\kill
+% \argcmd{\rtp}{label}|{abc}|
+% \>\>~ $\rightarrow$ \cmd{\label}\rmeta{type\,:\,}{abc}\\
+% \argcmd{\rtp}{label}\texttt{[\opt{key}=xxx:]}|{abc}|
+% \>\>~ $\rightarrow$ \cmd{\label}|{xxx:abc}|
+% \end{Itabb}
+% \blankline
+%
+% \noindent
+% \textbf{\slshape Examples:}
+%
+% \begingroup
+% \begin{Ipara}
+% Let $z = x+\mathrm{i} y$ and $\alpha = \beta + \mathrm{i}
+% \gamma$, with $\mathrm{i}^2 = -1$, then
+% \begin{align}

+% \spestag{e1}\\
+% &z^\alpha = \mathrm{e}^{\alpha \ln z}
+% \spestag{e2}\\
+% \intertext{\Eqref{e1,e2} lead to the following interesting results:}

+% \section{\pkg{Keyval} Optional Arguments}\seclabel{keyvals}
+%
+% Al the options for the referencing commands are set with a key-value
+% list. \Tabref[vref]{refopt} gives a full list of all the key-values and
+% defaults. The options can also be changed locally with the
+% \okeylst\ optional arguments.
+%
+%
+% \subsection{Identifier: \opt{key}}
+%
+% The \opt{key} key-value is the prefix to the reference label
+% of the \cmd{\label}, \cmd{\ref}, and \cmd{\pageref} commands.
+% The default is \opt{key=}\meta{type\,:\,}.
+% For reference to tables defined with the template
+% in \secref{tabtemp}:
+%
+% \begin{Itabb}
+% \tab\=\hspace{3.5cm}\=\hspace{2em}\=\kill
+% \cmd{\newref}|{tab}{...}|\\[1ex]
+% \>|\tablabel{abc}|
+% \>~ $\rightarrow$ |\label{tab:abc}|\\
+% \>|\tabref{abc}|
+% \>~ $\rightarrow$ |table~\ref{tab:abc}|\\[1ex]
+
+% \cmd{\newref}|{tab}{key=xxx-,...}|\\[1ex]
+% \>|\tablabel{abc}|
+% \>~ $\rightarrow$ |\label{xxx-abc}|\\
+% \>|\tabref{abc}|
+% \>~ $\rightarrow$ |table~\ref{xxx-abc}|
+% \end{Itabb}
+% For existing documents containing labels such as |\label{tab:xx}|,
+% you can define \opt{key}|={}| and use the existing labels with
+% \pkg{refstyle}, e.g.: |\tabref{tab:xx}|.
+%
+%
+% \subsection{Plural form: \opt{s}}
+%
+% The \opt{s} conditional option (\texttt{true/false}) switches the
+% singular/plural form of the reference on and off. The default is
+% \opt{s}\texttt{=true}, but it is initialized to \texttt{false}.
+% \begin{Itabb}
+% \tab\=\hspace{3.5cm}\=\hspace{2em}\=\kill
+% |\tabref{abc}|
+% \>\>~ $\rightarrow$ |table~\ref{tab:abc}|\\
+% |\tabref[s]{abc}|
+% \>\>~ $\rightarrow$ |tables~\ref{tab:abc}|
+% \end{Itabb}
+%
+%
+% \subsection{Extended reference: \opt{vref}}
+%
+% The \opt{vref} conditional option (\texttt{true/far/false}) switches the
+% \pkg{varioref} page referencing on and off. The default is
+% \opt{vref}\texttt{=true}, but it is initialized to \texttt{false}.
+%
+% \begin{Itabb}
+% \tab\=\hspace{3.5cm}\=\hspace{2em}\=\kill
+% |\tabref{abc}|
+% \>\>~ $\rightarrow$ |table~\ref{tab:abc}|\\
+% |\tabref[vref]{abc}|
+% \>\>~ $\rightarrow$ |table~\ref{tab:abc}|
+% |\vpageref[\unskip]{tab:abc}|\\
+% |\tabref[vref=far]{abc}|^^A
+% \>\>~ $\rightarrow$ |table~\ref{tab:abc}|
+% |\reftextfaraway{tab:abc}|
+% \end{Itabb}
+%
+%
+% \subsection{External interfaces: \opt{xr}}
+%
+% The \opt{xr} option is for references to external documents.
+% It inserts a prefix in the reference label, compatible with the
+% \pkg{xr} package. The default is \opt{xr}|={}|.
+%
+% External document can be defined in the preamble with the
+% \pkg{xr} package:
+% \begin{Ipara}
+% \cmd{\usepackage}|{xr}|\\
+% \cmd{\externaldocument}\oarg{xr\_key}\marg{filename}
+% \end{Ipara}
+%
+% \noindent
+% If, for example, an external document defined with
+% \meta{xr\_key}\texttt{=\{A-\}}, uses an identical setup (the same
+% \file{refstyle.cfg}), then it can be referenced with
+%
+% \begin{Itabb}
+% \tab\=\hspace{3.5cm}\=\hspace{2em}\=\kill
+% |\tabref[xr=A-]{abc}|
+% \>\>~ $\rightarrow$ |table~\ref{A-tab:abc}|
+% \end{Itabb}
+% \noindent or otherwise
+% \begin{Itabb}
+% \tab\=\hspace{3.5cm}\=\hspace{2em}\=\kill
+% |\tabref[xr=A-,key=]{abc}|
+% \>\>~ $\rightarrow$ |table~\ref{A-abc}|
+% \end{Itabb}
+%
+
+%
+% \subsection{Language parameters: \opt{name}, \opt{names},
+% \opt{Name}, \opt{Names}, \opt{rngtxt}, \opt{lsttxt}}
+% \seclabel{langopts}
+%
+% This key-values contain the text prefixes and insertions.
+% Every house style or user has his or her own preference for naming the reference types,
+% therefore are there no defaults provided.
+%
+% \begin{Itabb}
+% \hspace*{1.5cm}\=\hspace{7cm}\=\kill
+% \opt{name} \> ---~Inside sentence reference prefix (singular)
+% \> default=|{}|\\
+% \opt{names}\> ---~Inside sentence reference prefix (plural)
+% \> default=|{}|\\
+% \opt{Name} \> ---~First word reference prefix (singular)
+% \> default=|{}|\\
+% \opt{Names}\> ---~First word reference prefix (plural)
+% \> default=|{}|\\
+% \opt{rngtxt}\> ---~Range of references
+% \> default=|{\ to~}|\\
+% \opt{lsttxt}\> ---~List of references
+% \> default=|{\ and~}|
+% \end{Itabb}
+% \noindent
+% Good typographic style manuals recommend the minimum use of
+% capital letters and punctuation that breaks the flow of a sentence
+% or paragraph. For abbreviations, Bringhurst\cite{Bring1996}
+% recommends the Oxford house style: Use a period only when the word
+% stops prematurely. The period is omitted if the abbreviation
+% begins with the first letter and end with the last. As an example
+% for equations, use eq.~(1) or eqn~(1).
+% A good guideline is not to abbreviate any reference type names.
+% If a sentence starts with a
+% reference then the type name must always be written in full.
+% A typical example for references to a table is:
+% \begin{Ipara}
+% \opt{name}| ={table~}, |\opt{names}| ={tables~},|\\
+% \opt{Name}| ={Table~}, |\opt{Names}| ={Tables~},|\\
+% \opt{rngtxt}|={\ to~}, |\opt{lsttxt}|={\ and~},|
+% \end{Ipara}
+% Note the hardspace after the text. It is needed to keep the text
+% and the reference together on the same line.
+%
+% The \RS\ configuration file can be setup to interface with \pkg{babel}
+% for different languages or for automatic language changes inside a
+% document. The language specific key-values can be added to the
+% \pkg{babel} hook |\extras|\meta{language}. The command
+% \DescribeMacro{\DeclareLangOpt}\cmd{\DeclareLangOpt}\footnote{^^A
+% Only for use in \texttt{refstyle.cfg} the default config file}
+% is provided to supply a \meta{language} option to the package
+% and to add the option contents to |\extras|\meta{language}. The
+% default config file contains the following lines for equations:
+% \begin{Ipara}
+% |\newcommand\RSenglish{% |\\
+% | \def\RSeqtxt{equation~}% |\\
+% | \def\RSeqstxt{equations~}%|\\
+% | \def\RSEqtxt{Equation~}% |\\
+% | \def\RSEqstxt{Equations~}%|\\
+% | : |\\
+% | } |\\
+% |\DeclareLangOpt{english}{\RSenglish}|
+% \end{Ipara}
+% The key-value options for language specific options
+% are then set as:
+% \begin{Ipara}
+% |\newref{eq}{% |\\
+% | name = \RSeqtxt, |\\
+% | names = \RSeqstxt,|\\
+% | Name = \RSEqtxt, |\\
+% | Names = \RSEqstxt,|\\
+% | : |\\
+% | } |
+% \end{Ipara}
+%
+% \noindent\LaTeX{}/\pkg{babel} provides some language specific
+% names that can be utilized.
+%
+% \begin{Ipara}
+% |\chaptername \appendixname|\\
+% |\figurename \tablename|\\
+% |\partname \pagename|
+% \end{Ipara}
+%
+% To setup a multilingual document with \pkg{babel},
+% \emph{always} make the language options global so that other
+% language compliant packages can detect it.
+% A typical setup for an Afrikaans/English document would be:
+% {\makeatletter\def\meta@font@select{\normalfont\ttfamily\slshape}
+% \begin{Ipara}
+% |\documentclass[UKenglish,afrikaans,|\meta{options}|]{|\meta{LaTeX\_class}|}|\\
+% |\usepackage[T1]{fontenc}%..|\texttt{\slshape hyphenation of words with accents}\\
+% |\usepackage{babel}%........|\texttt{\slshape language def's}\\
+% |\usepackage{varioref}%.....|\texttt{\slshape for \opt{vref} option}\\
+% |\usepackage{refstyle}|
+% \end{Ipara}}
+%
+%
+% \subsection{Reference formatting command: \opt{refcmd}}
+%
+% The \opt{refcmd} key-value holds the contents of the internal
+% command that formats the reference. The |#1| parameter
+% passed to the command is the full reference label.
+% For example:
+% \begin{Itabb}
+% \hspace{10em}\=hspace{5em}\=\kill
+% \opt{refcmd}|=(\ref{#1})| \> $\rightarrow$~
+% |(\ref{|\meta{label}|})|
+% \end{Itabb}
+%
+% External commands can be employed. For example, to make references
+% to equations identical to the \AmS\ \cmd{\eqref} command:
+% \begin{Itabb}
+% \opt{refcmd}|={\textup{\tagform@{\ref{#1}}}}%|~~It needs \file{amsmath.sty}
+% \end{Itabb}
+%
+% The \opt{refcmd} can be used in conjuntion with the |\ifRSstar|,
+% |\ifRSnameon|, |\ifRSplural| and |\ifRScapname| internal
+% conditional variables to format the reference. As an example for a
+% reference to a footnote, where a duplicate footnote mark is needed,
+% can the \opt{refcmd} be configured so that the starred form of the
+% reference command produce a superscripted duplicate mark:
+% \begin{Itabb}
+% |\newcommand{\RSfnmark}[1]{%|\\
+% | \begingroup |\\
+% | \unrestored@protected@xdef\@thefnmark{#1}%|\\
+% | \endgroup |\\
+% | \@footnotemark} |\\[1ex]
+% \opt{refcmd}|={\ifRSstar\RSfnmark{\ref{#1}}\else(\ref{#1})\fi}|
+% \end{Itabb}
+% \noindent The second footnote mark, \fnref*[name]{b}, in
+% \tabref[vref]{refopt}, was obtained in this way with the reference
+% |\fnref*{b}|. See \secref{ChapTempl} for another
+% example for references to chapters and appendices.
+%
+% The \pkg{nameref} package can easily be incorporated if you need elaborate
+% references which include the section or chapter name:
+% \begin{Ipara}
+% |\Secref[vref, refcmd={\S\ref{#1}, `\nameref{#1}'}]{PRefCmds}|
+% \end{Ipara}
+% gives
+% \begin{Ipara}
+% \Secref[vref, refcmd={\S\ref{#1}, `\nameref{#1}'}]{PRefCmds}
+% \end{Ipara}
+%
+% \clearpage
+% \section{Default configuration file}
+%
+% The default configuration file, \file{refstyle.cfg}, makes the
+% following declarations:
+% \begin{Ipara}
+% |\newref{part}{...}| \quad$\rightarrow$ Parts\\
+% |\newref{chap}{...}| \quad$\rightarrow$ Chapters and Appendices\\
+% |\newref{sec}{...} | \quad$\rightarrow$ Sections\\
+% |\newref{eq}{...} | \quad$\rightarrow$ Equations\\
+% |\newref{fig}{...} | \quad$\rightarrow$ Figures\\
+% |\newref{tab}{...} | \quad$\rightarrow$ Tables\\
+% |\newref{fn}{...} | \quad$\rightarrow$ Footnotes
+% \end{Ipara}
+% If there is a need for more reference types, this standard
+% list can be expanded.
+%
+% At this stage the packages also contains language definitions for
+% \texttt{afrikaans} and \texttt{english}. Other language definitions
+% will be included if sent to me.
+%
+% \section{Example Templates for the \RS Package}\seclabel{templates}
+%
+% The user can also define his or her own templates and put it
+% in a configuration file to ensure uniformity
+% of reference formats in your documents.
+%
+% In this section a number of reference templates are given as
+% examples. A sample configuration file can be generated by running
+% \file{refstyle.dtx} through \pkg{docstrip} with the \opt{<tmpl>}
+% option. Modify \file{reftmpl.cfg} according to your requirements
+% and place it in a directory where \TeX\ can find it.
+%
+% \subsection{Document divisions}
+% \subsubsection{Parts}
+%
+% References to parts are usually straight forward, except that the
+% document division ``Part'' must be distinguished from the normal
+% usage of the word ``part'' in a sentence. A personal preference
+% is to use small caps.
+%
+% \begin{RSframed}
+% \begin{macrocode}
+%<*tmpl>
+%%--- TEMPLATE FOR PARTS -------------------------
+% \end{macrocode}
+% \begin{macrocode}
+ \newref{part}{%
+ name = {Part~},
+ names = {Parts~},
+ Name = {Part~},
+ Names = {Parts~},
+ rngtxt = {\space to~},
+ lsttxt = {\space and~}}
+% \end{macrocode}
+% \end{RSframed}
+%
+%
+%
+% \subsubsection{Chapters and Appendices}\seclabel{ChapTempl}
+%
+% A major problem with a reference to a chapter is that at the time
+% when the reference label, |\label|\marg{chap-label}, is created,
+% it is unknown whether it would eventually ends up in the main
+% matter or the appendix part of a book or report.
+%
+% A simple solution is to use the prefix to the \meta{chapter}
+% counter, |\p@chapter|, to write the definition of |\@chapapp| to
+% the auxiliary file (|.aux|) together with information of the
+% label. The command |\@chapapp| expands to either |\chaptername| or
+% |\appendixname| depending on whether the reference label is
+% defined in the main matter or after the |\appendix| was called.
+% (Note that |\@chapapp| is not defined in the \AmS\ book class.)
+%
+% \begin{Ipara}
+% |\renewcommand*{\p@chapter}{\string\chname{\@chapapp}}|\\
+% |\newcommand*{\chname}[1]{}%<-make it harmless |\\
+% |\newcommand*{\chapref}[1]{{\renewcommand*{\chname}[1]{##1~}\ref{#1}}}|
+% \end{Ipara}
+%
+% \noindent The reference to a chapter, |\chapref|\marg{chap-label},
+% will then be prefixed with |\chaptername| or |\appendixname| and
+% it does not matter where it was defined or where it was called.
+%
+% To utilize the full functionality of the \RS package for
+% references to chapters and appendices, a complex form of
+% \cmd{\newref} needs to be implemented.
+% The following is an example
+% of a template for a book or report classes.
+%
+%
+% \begin{RSframed}

+% \subsection{Footnotes}\seclabel{fnTempl}
+%
+% A reference to a footnote differs from other references in that
+% it is only defined inside the footnote definition itself:
+% \begin{Ipara}
+% |\footnote{This is a footnote ... \label{fn:xx}}|
+% \end{Ipara}
+% It can then be referred to with |\ref{fn:xx}|.
+% A useful application of the \RS package is for references to
+% footnotes, were you need a duplicate footnote mark that refers to
+% a previously defined footnote. You can use the stared form of the reference
+% command to format the reference as a footnote mark, while the
+% reference commands without a star behave as normal. The second
+% footnote mark, \fnref*{b}, in \tabref[vref]{refopt}, was obtained with
+% the reference: |\fnref*{b}| while |\fnref[vref]{b}| gives: \fnref[vref]{b}.
+%
+% \begin{RSframed}
+% \begin{macrocode}
+%%--- TEMPLATE FOR FOOTNOTES --------------------
+% \end{macrocode}
+% Define the \cmd{\RSfnmark} to reproduce the footnote mark.
+% Use the |\ifRSstar| conditional to switch between a superscripted

+ lsttxt = {\space and~}}
+% \end{macrocode}
+% \end{RSframed}
+%
+% \subsection{Enumerated lists}
+%
+% A reference to an item in an enumerated list can be obtained
+% by placing the labelling command after the \cmd{\item} command
+% inside the list. The second level numbering of the \cmd{\ref}
+% label in the standard \LaTeX{} is: 2a, 2b, etc.
+%
+% If you want to change the reference labels to 2(a), 2(b),
+% etc., without effecting the display in the \env{enumerate}
+% environment, you can make the following redefinition:
+% \begin{Ipara}
+% |\makeatletter|\\
+% |\renewcommand{\p@enumii}{\expandafter\p@@enumii}|\\
+% |\newcommand{\p@@enumii}[1]{\theenumi(#1)}|\\
+% |\makeatother|
+% \end{Ipara}
+% The contents of the \cmd{\@currentlable} is then
+% \begin{Ipara}
+% |{\expandafter\p@@enumii\theenumii}| ~$\rightarrow$~
+% |{\theenumi(\theenumii)}|
+% \end{Ipara}
+%
+% Writing a template for enumerated lists is left to the user.
