+%
+% \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}] package option,
+% which uses code from packages \Xpackage{alphalph} and \Xpackage{engrec}.
+%
+% 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<.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}                                &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}]          &prints: \refitem{commaref-myList,2,1}[\ref.\ref].                                      \\
+% \cs[\red]{refitem}\M*{myList,2,1}\M*[\cs{label}\cs{ }\cs{label}] &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}}} & \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}] & \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}] & \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}} & \refitem{refitem-myList2{2}{first description label }} \\
+% \cs[\red]{refitem}\M*{myList2\M*{2}\M*{first description label}}\M*[\cs{ref\stf}, \cs{label}] & \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}] & \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}                                      &\refitem{Important subitem}                       \\
+% \cs[\red]{refitem}\M*{Important subitem}\M*[\cs{label}\cs{ }\cs{label}]       &\refitem{Important subitem}[\label\ \label]       \\
+% \cs[\red]{refitem}\M*{Important subitem}\M*[\cs{ref\stf} sub point \cs{ref}] &\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:
+%
+% \begin{tabu}{lX[c]X}
+% \cs[\red]{refitem}\M*{2.1,2,3}               &\refitem{2.1,2,3}               &in the \hyperref[commarefscheme]{\emph{commaref}} scheme \\
+% \cs[\red]{refitem}\M*{2.1\M*{2}\M*{3}}       &\refitem{2.1{2}{3}}             &in the \hyperref[refitemscheme]{\emph{refitem}} scheme   \\
+% \cs[\red]{refitem}\M*{for further reference} &\refitem{for further reference} &in the \hyperref[userscheme]{\emph{user}} scheme   \\
+% \end{tabu}
+%
+% \medbreak
+%
+% To name your lists automatically it is also possible to use (these are examples):
+%
+% \begin{itemize}[itemsep=0pt,topsep=0pt]
+% \item \xpackage{interfaces-hypbmsec} with package \xpackage{hypbmsec}:\\
+%         \textt{name\stform* = \cs{csname} the\cs{lastsectionname}\cs{endcsname}}
+% \item package \xpackage{refcount}: \textt{name\stform* = \cs{getrefbykeydefault}\M*{reference}\M*{anchor}\M*{default}}.
+% \end{itemize}
+%
+%
+% \subsection(Making references: \cs{refitem}){Referencing the items : \csbf[\rred]{refitem}}
+% \label{refitem}
+%
+% \begin{declcs}{refitem}\M{reference}\M*[text with properties \cs{ref}, \cs{label} \etc.]\textsuperscript{babel}\\
+%              \cs{refitem}\stform* \\
+% \end{declcs}
+%
+% \thispackage provides \cs{refitem} to reference the items of lists with the following possible syntaxes:
+%
+% \tabulinestyle{dotted=on 1pt off2pt,dash=\hbox{$\scriptscriptstyle\mkern2mu\cdotp\mkern2mu$}}
+%
+% {\tabcolsep=4pt
+% \begin{tabu}{X[-1]<{\cellstrut}X} \toprule      \savetabu{refitem}
+% \cs{refitem}\M*{\textcolor{reference}{refname}}\M*[\textcolor{properties}{properties}]
+%                 & displays a reference to \textt{\dg refname}                    \par
+%                    the text displayed depends on the optional \textcolor{properties}{\textt{properties}} \par
+%                    whose default value is \cs{ref}. \\ \tabucline[dash]-
+% \cs{refitem}\stform*\M*{\textcolor{reference}{refname}}\M*[\textcolor{properties}{properties}]
+%                 & 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

+%       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

+%

+% \end{declcs}
+%
+% For reference to external files (to make hyperlinks), \cs{refitem} can be invoked with the following syntax:
+%
+% \begin{tabu}{X[-1]<{\cellstrut}X}\toprule
+% \cs{refitem}\M*[file:\textellipsis]\M*{{\dg refname}}\M*{{\bf text}}

+%                 & 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}''
