%
% \thispackage, as a companion package for \Xpackage{enumitem}, extends the references mechanism
% for lists of items and allows hyperlinks to any items in lists formatted by \xpackage{enumitem}.
% Hyper-references to lists seems not always necessary, but their importance rise much when a document
% contains lists that can stretch out on several pages.
%
% Primarily intented for \texttbf{enumerate} environments (\ie numbered lists),
% \thispackage* can also reference any item in \texttbf{description} or \texttbf{itemize}
% environments: restrictions can be set with the \hyperref[package options]{package options}.
%
% A \hyperref[sec:naturalrefscheme]{natural reference scheme} for referencing items anywhere in the
% document is provided with three modalities (the \hyperref[commarefscheme]{\emph{commaref}} scheme,
% the \hyperref[refitemscheme]{\emph{refitem}} scheme and the \hyperref[userscheme]{\emph{user}} scheme).
% The references can be typeset differently with the command
% \hyperref[refitem]{\cs{refitem}}, its options and eventually arbitrary text.
%
% Additionnally, \thispackage* allows to typeset greek-enumerated lists with the
% \refitem{package options{greek}}[\textt{greek}] or \refitem{package options{greekctr}}[\textt{greekctr}]
% package options, which use code from packages \Xpackage{alphalph} and \Xpackage{engrec} or \Xpackage{greekctr}.
%
% References to items in external documents compiled with \xpackage{enumitem-zref} is also possible
% with \hologo{pdfTeX}\footnote{This is not \xpackage{xr} but ``pure'' \pdf.}.
%
% \thispackage* requires and is based on the packages \xpackage{enumitem} by Javier Bezos
% and \Xpackage{zref} by Heiko Oberdiek.
% It works with an \eTeX{} distribution of \LaTeX.

% \subsection{Numbered lists, not numbered lists and \texorpdf\xpackage{hyperref}}
% \label{sec:numberedlists}
%
% \LaTeX{} defines two ``classes'' of lists of items:
% \begin{itemize}[leftmargin=1cm]
% \item \texttbf{enumerate} lists which are \textit{numbered} (\ie a counter gives an index to each item in the list),
% \item \texttbf{description} and \texttbf{itemize} lists which are \textit{not numbered} (no counter, thus no index).
%\end{itemize}
%
% When \xpackage{hyperref} is used in \textit{numbered lists}, each \cs{item} gives \xpackage{hyperref}
% the opportunity to define an anchor, whose name is chosen considering the current value of the \emph{index}.
%
%
% Different cases have to be considered:
% \begin{enumerate}[label=\arabic*),name=numberedlists,leftmargin=1cm]
% \item We are in a \emph{numbered} list (\ie \textt{enumerate}):
%     \begin{enumerate}[label=\roman*),leftmargin=*]
%     \item if the item is automatic (\cs{item} without option), \xpackage{hyperref} puts an anchor named \texttt{Item.IDX}.
%     \item if the item is user defined (\cs{item}\M*[user item]), \xpackage{hyperref} does not put an anchor.
%     \end{enumerate}
% \item We are not in a \emph{numbered} list (\ie \texttt{description} or \texttt{itemize}):
%     \begin{enumerate}[label=\roman*),leftmargin=*]
%     \item[] \xpackage{hyperref} does not put an anchor.
%     \end{enumerate}
% \end{enumerate}
%
% Moreover, when \xpackage{hyperref} is loaded, the expansion of the \cs{label} command leads to the expansion of the item label
% (with \cs{protect}) for it is written to the \xext{aux} file:
% \begin{itemize}
% \item in the case \refitem{numberedlists{1}{i}}[\ref*\,\ref]
% \item and also in the case \refitem{numberedlists{1}{ii}}[\ref*\,\ref] if:
%     \begin{itemize}[label=-]
%     \item the list is a \textt{description} list, and
%     \item package \xpackage{nameref} is loaded, and
%     \item the \cs{label} command appears inside the \textt{user item} text.
%     \end{itemize}
% \end{itemize}
%
%
% {\flushright\smaller\lk I was guardedly affraid about those rules when I understood them, as you may be...\par}
%
% \thispackage adds an anchor in the cases \refitem{numberedlists,1,2}[\ref*\,\ref] and \refitem{numberedlists,2}.
% The item label text is always expanded (with \cs{protect} and \xpackage{babel} protection).
%
%
% \subsection(A "natural" reference scheme for lists){A ``natural'' reference scheme for lists}
% \label{sec:naturalrefscheme}
%
% \thispackage provides \textbf{3 ways} to reference a specific item in a list. The first 2 can be used to reference
% items in lists of external documents as well.
%
% References are made with the command: \csref{refitem}, but \cs{hyperref} can be used as well.
%
% \makeatletter
% \newrobustcmd*\presitem{\@ifstar\presitem@star\presitem@nost}
% \newrobustcmd*\presitem@nost[1]{this is the item \presitem@star{#1}}
% \newrobustcmd*\presitem@star[1]{\ifdim\lastskip&lt;.4em\unskip\hskip.4em\fi\textcolor{reference}{\textt{#1}}}
% \newrobustcmd*\namelist[1]{\texttt{`#1'}}
% \makeatother
%
% \cs{subitem} and \cs{subsubitem} provided in some classes cannot be referenced with \thispackage*.
%
% \subsubsection(The commaref scheme){The \textit{\db commaref} scheme}
% \label{commarefscheme}
%
% Assuming you gave a name to your \textt{enumerate}, \textt{description} or \textt{itemize} list,
% and let's say this name is \namelist{myList}, each item is given an index.
% Any item is indexed, whether it's printed by the mean of a user item or an an automatic item.
% Then:
% \begin{itemize}[name=commaref-myList]
%  \item \presitem{myList,1}
%  \item \presitem{myList,2}
% \begin{itemize}[itemindent=2cm,font=\bfseries]
%  \item \presitem{myList,2,1}
%  \item \presitem{myList,2,2}
%  \item [user-defined] \presitem{myList,2,3}
% \end{itemize}
%\end{itemize}
%
% Reference to the third item can be made with:
%
% \begin{tabu}{lX}
% \cs[\red]{refitem}\M*{myList,2,1}                                &amp;this prints: \refitem{commaref-myList,2,1} for it is the first item in the inner list. \\
% \cs[\red]{refitem}\M*{myList,2,1}\M*[\cs{ref}.\cs{ref}]          &amp;prints: \refitem{commaref-myList,2,1}[\ref.\ref].                                      \\
% \cs[\red]{refitem}\M*{myList,2,1}\M*[\cs{label}\cs{ }\cs{label}] &amp;prints: \refitem{commaref-myList,2,1}[\label\ \label].
% \end{tabu}
%
%
% Nothing simplest, no more comment...
%
% \subsubsection(The refitem scheme){The \textit{\db refitem} scheme}
% \label{refitemscheme}
%
% \begin{enumerate}[label=\Alph*),name=refitem-myList]
% \item \presitem{myList\M*{A}}.
% \item \presitem{myList\M*{B}} (as you'd have expected...)
%     \begin{enumerate}[label=\roman*)]
%     \item \presitem{myList\M*{B}\M*{i}}. \\
%            and is \emph{also} \presitem*{innerlist\{i\}} if this nested list has been named \namelist{innerlist}.
%     \item \presitem{myList\{B\}\{ii\}} \quad (or \presitem*{innerlist\{ii\}}).
%        \begin{enumerate}[label=\engrec*)\ ,ref=\engrec*]
%        \item \presitem{myList\{B\}\{ii\}\{\string\alpha\}} (with the package option \texttt{[greek]}).
%        \item \presitem{myList\{B\}\{ii\}\{\string\beta\}} \quad (or \presitem*{innerlist\{ii\}\{\string\beta\}}).
%        \end{enumerate}
%     \end{enumerate}
% \item \presitem{myList\{C\}} (as you'd have expected...)
% \item[\textbf{perso}] \presitem{myList\{perso\}}.
% \item \presitem{myList\{D\}} and is also \presitem*{myList,5} in the \textit{commaref} scheme.
%     \begin{itemize}
%     \item \presitem{myList\{D\}\{1\}}
%     \item \presitem{myList\{D\}\{2\}} \\
%           inside \textt{itemize} lists, labels are replaced by their arabic index in the \textit{refitem} scheme.
%     \end{itemize}
% \end{enumerate}
%
% And here is a reference to:
%
% \begin{tabu}{lX}
% \cs[\red]{refitem}\M*{myList\M*{B}\M*{ii}\M*{\cs{alpha}}} &amp; \refitem{refitem-myList{B}{ii}{\alpha}} \\
% \cs[\red]{refitem}\M*{myList\M*{B}\M*{ii}\M*{\cs{alpha}}}\M*[\cs{label}\cs{ }\cs{label}\cs{ }\cs{label}] &amp; \refitem{refitem-myList{B}{ii}{\alpha}}[\label\ \label\ \label] \\
% \cs[\red]{refitem}\M*{myList\M*{B}\M*{ii}\M*{\cs{alpha}}}\M*[\cs{label\stf}-{}-\cs{label\stf}-{}-\cs{label}] &amp; \refitem{refitem-myList{B}{ii}{\alpha}}[\label*--\label*--\label] \\
% \end{tabu}
%
% Now what happens with a description list:
%
% \begin{enumerate}[label=\arabic*\textdegree),name=refitem-myList2]
% \item \presitem{myList\M*{1}}
% \item \presitem{myList\M*{2}}
%        \begin{description}
%        \item [First description label]  \presitem{myList\M*{2}\M*{first description label}}
%        \item [And a second one]         \presitem{myList\M*{2}\M*{and a second one}}
%        \end{description}
% \item \presitem{myList\M*{3}}
% \end{enumerate}
%
% \begin{tabu}{lX}
% \cs[\red]{refitem}\M*{myList\M*{2}\M*{first description label}} &amp; \refitem{refitem-myList2{2}{first description label }} \\
% \cs[\red]{refitem}\M*{myList2\M*{2}\M*{first description label}}\M*[\cs{ref\stf}, \cs{label}] &amp; \refitem{refitem-myList2{2}{first description label }}[\ref*, \label] \\
% \cs[\red]{refitem}\M*{myList2\M*{2}\M*{first description label}}\M*[\cs{ref}\cs{ }\cs{ref}] &amp; \refitem{refitem-myList2{2}{first description label }}[\ref\ \ref] \\
% \end{tabu}
%
% The correspondance between the reference name and the reference that is finally printed is immediate:
% the \emph{refitem} scheme is almost useful when used with \xpackage{hyperref}.
%
% The list name \textt{myList} is case sensitive, but the item number \M*{B} or \M*{first description label} is not.
% This can be changed with the \refitem{package options{CaSeS}} package option. Trailing spaces in the item label
% are always removed from the reference name in the \hyperref[refitemscheme]{\emph{refitem}} scheme.
%
%
% \subsubsection({The user scheme (\cs{label})}){The \textit{\db user} scheme: with the \cs{label} command}
% \label{userscheme}
%
% \begin{enumerate}[label=\arabic*\,\textendash,name=user-myList,ref=\arabic*]
% \item \presitem{myList,1} and \presitem*{myList\{1\}} and as long as I type \cs{label}\M*{Important Item} it is also named \presitem*{Important Item}.
% \item \presitem{myList,2} and \presitem*{myList\{2\}}.
%     \begin{enumerate}[label=\alph*)\ ]
%     \item \presitem{myList,2,1} and \presitem*{myList\{2\}\{a\}}.
%     \item \presitem{myList,2,2} and \presitem*{myList\{2\}\{b\}} and as long as I type:\\
%           \cs{label}\M*{Important subitem} it is also named  \presitem*{Important subitem}. \label{Important subitem}
%     \end{enumerate}
% \end{enumerate}
%
% Then you get:
%
% \begin{tabu}{X[-5]X}
% \cs[\red]{refitem}\M*{Important subitem}                                      &amp;\refitem{Important subitem}                       \\
% \cs[\red]{refitem}\M*{Important subitem}\M*[\cs{label}\cs{ }\cs{label}]       &amp;\refitem{Important subitem}[\label\ \label]       \\
% \cs[\red]{refitem}\M*{Important subitem}\M*[\cs{ref\stf} sub point \cs{ref}] &amp;\refitem{Important subitem}[\ref* sub point \ref]
% \end{tabu}
%
% The reference is case sentitive.
%
% \section{User Interface}
% \label{sec:userinterface}
%
% \subsection{Naming lists}
%
% To use the reference schemes defined by \thispackage, it is necessary to give lists a name. For that purpose,
% two new keys: \textt{name}\, and\, \textt{name\stform*} have been added to the keys provided by \xpackage{enumitem}.
%
% The key \textt{`name'} gives a name to the list, while \textt{name\stform*} is a bit more clever
% and should be used in every circonstances when lists are nested, almost when lists are automatically
% named by the mean of the paragraph they belong to. Example:
%
% \begin{Verb*}
%  \newlist{myList}{enumerate}{3}
%  \setlist[myList]{ label* = \arabic*.,  name* = \arabic{section}.\arabic{subsection}}
% \end{Verb*}
%
% In case of nested lists,\, \texttt{name\stform*}\, will compare the name you gave to the list with the name
% of its parent list, and ignore the key in case of equality.
%
% This gives:
%
% \newlist{naming-myList}{enumerate}{3}
% \setlist[naming-myList]{ label*=\arabic*., name* = \arabic{section}.\arabic{subsection}}
%
% \begin{naming-myList}[itemsep=0pt]
% \item First item
% \item Second item
%     \begin{naming-myList}[itemsep=0pt]
%     \item sub item
%     \item another sub item
%     \item a last sub item \cs{label}\M*{for further reference} \label{for further reference}
%     \end{naming-myList}
% \end{naming-myList}
%
% And then:

%              \cs{refitem}\stform* \\
% \end{declcs}
%
% \thispackage provides \cs{refitem} to reference the items of lists with the following possible syntaxes:
%
% {\tabcolsep=4pt
% \begin{tabu}{X[-1]&lt;{\cellstrut}X} \toprule      \savetabu{refitem}
% \cs{refitem}\M*{\textcolor{reference}{refname}}\M*[\textcolor{properties}{properties}]

%                 &amp; can be used when you want a reference but no hyperlink. \\ \bottomrule
% \end{tabu}}
%
% If the reference \textcolor{reference}{\textt{rename}} does not point to an item, \cs{refitem}
% behaves like \cs{ref} (or \cs{ref\stf}) and the \M*[properties] are ignored.
% A warning is displayed in the \xext{log} file.
%
% The properties available with \cs{refitem} are:
%
% \begin{enumerate}[labelwidth=2.4cm,leftmargin=2.6cm,align=left]
% \item [\csbf{ref}] This is the default property: the same as \LaTeX's \cs{ref} command: it expands
%       to the text corresponding to the \textt{ref} key of the \xpackage{enumitem} list environment,
%       which by default is:
%       \begin{itemize}[leftmargin=1cm]
%       \item in \textt{enumerate} lists: the same as the \textt{label}.
%       \item in \textt{itemize} lists: the index of the item.
%       \item in \textt{description} lists: the user defined label, or if no label has been given to
%             the \cs{item} command, the index of the item.
%       \end{itemize}
% \item [\csbf{label}] The label is printed, whatever value the \textt{ref\ key} has been given. For \textt{description},
%      the label may be empty.
% \item [\csbf{label\stf} \csbf{ref\stf}] This is a variant of \cs{label}: automatic labels in \textt{enumerate} lists are related
%       to a counter. \cs{ref\stf} or \cs{label\stf} prints the formatted value of the counter, without any text around.
%       For \textt{itemize}, \textt{description} or user items inside \textt{enumerate} lists, this is the same as \cs{label}.
% \item [\cs{page}] The same as \cs{pageref}.
% \item [\cs{name}] The name that has been given to the list.
% \item [\cs{depth}] The depth of the list (equal to\, \textt 1\, if the list is not nested).
% \item [\cs{index}] The index of the item; user defined items are counted.
% \item [\cs{listctr}] The item number inside numbered lists (\ie \textt{enumerate}); user defined items are not counted:
%        this is the value of the counter \cs{@listctr}.
% \item [\cs{type}] The type of the list (\ie \textt{enumerate}, \textt{itemize} or \textt{description})
% \item [\cs{refitem}] The list of references names that can be invoked with \cs{refitem} for this specific item
%       in the \hyperref[refitemscheme]{\emph{refitem}} scheme (see also \csref{zeninfo}).
% \item [\cs{commaref}] The list of references names that can be invoked with \cs{refitem} for this specific item
%       in the \hyperref[commarefscheme]{\emph{commaref}} scheme (see also \csref{zeninfo}).
% \end{enumerate}
%
% \begin{declcs}{refitem}\M*[file:\textellipsis]\M{reference}\M{text}\textsuperscript{babel}
% \end{declcs}
%
% For reference to external files (to make hyperlinks), \cs{refitem} can be invoked with the following syntax:
%
% \begin{tabu}{X[-1]&lt;{\cellstrut}X}\toprule
% \cs{refitem}\M*[file:\textellipsis]\M*{{\dg refname}}\M*{{\bf text}}
%                 &amp;Can be used for references to an external \xext{pdf} file. \\ \tabucline[dotted]-
% \cs{refitem}\M*[]\M*{{\dg refname}}\M*{{\bf text}}
%                 &amp; The current file is used by default...
% \\ \bottomrule
% \end{tabu}
%
% Only the \hyperref[refitemscheme]{\emph{refitem}} and the \hyperref[commarefscheme]{\emph{commaref}} schemes can be used.
% The \hyperref[userscheme]{user} scheme cannot be used presently for external files. An implementation ``à la \xpackage{xr}''

%   \begin{Version}{2010/12/17 v1.5}\HistLabel{v1.5}
%   \item \thispackage now works with the keys: \textt{start=},\, \textt{resume},\, and\, \textt{resume\stf}\,
%         of \xpackage{enumitem} package.
%   \item Package option: \refitem{package options{greekctr}}[\textt{greekctr}] added as an alternative to the
%        \refitem{package options{greek}}[\textt{greek}] package option: \textt{greekctr} is based on the
%         \Xpackage{greekctr} package while \textt{greek} is based on \Xpackage{engrec}.
%         Both uses code of \Xpackage{alphalph} in order to make the counters \textsl{wrap} around the greek alphabet. \\
%         Options \refitem{package options{greek}}[\textt{greek}] and/or \refitem{package options{greekctr}}[\textt{greekctr}]
%         are automatically loaded \cs{AtBeginDocument} if the \xpackage{engrec} / \xpackage{greekctr} packages are detected.
