+% \subsection{Headers and Footers}
+% \label{sec:headers-footers}
+% \newfeature[v1.3] \pkg{ekdosis} provides a mechanism of its own for
+% emitting header and footer marks. The first operation consists in
+% recording the information to be printed as signpost by means of the
+% |mark| optional argument of the \cs{ekddiv} command described above
+% in \vref{sec:ekddiv}.
+%
+% \DescribeMacro{\ekdmark} Once this is done, \cs{ekdmark} can be
+% inserted in commands used to make headers and footers where the mark
+% is to be printed.
+%
+% A common layout is that of headers in which one finds printed in
+% sequence on even pages the page number, then the author's name, and
+% on odd pages the title of the edited text, then the current
+% division, then the page number, like so:---
+%
+% \needspace{4\baselineskip}
+% \begin{xltabular}{1.0\linewidth}{|XcX|}
+%   \multicolumn{3}{l}{Even pages:}\\
+%   \hline
+%   \cs{thepage} & Hippocratis & \\
+%   \hline
+%   \multicolumn{3}{l}{Odd pages:}\\
+%   \hline
+%    & Epidemiarum liber II, \cs{ekdmark} & \hfill\cs{thepage}\\
+%   \hline
+% \end{xltabular}
+%
+% To return to the example provided by \vref{lst:ekddiv-ex}, the mark
+% of the current division would be inserted in the third-level
+% \cs{ekddiv} command printed at line~28 like so:---
+%
+% \iffalse

+  \ekddiv{head=1, type=paragraph, depth=3, n=II.1.1, mark={1, 1}}
+\end{minted}
+% \iffalse
+%</example>
+% \fi
+%
+% The following example illustrates how the corresponding headers and
+% footers could be prepared in a straightforward way with the help of
+% the \pkg{titleps} package:\footcite{titleps}---

+\end{minted}
+% \iffalse

+% \fi
+%
+% \DescribeMacro{\endmark} It must be noted that \cs{ekdmark} is
+% designed to print the first mark that is emitted on a given page and
+% ignore the mark corresponding to any portion of text that may be
+% printed between the top of the page and the point where the first
+% mark is called. \cs{endmark} is an argument-less command that can be
+% used just at the end of that portion of text to instruct
+% \pkg{ekdosis} to print the last-emitted mark of the preceding page
+% instead of the first-emitted mark of the current page.
+%
+% \paragraph{Removing Headers and Footers}
+% Pages such as title pages must be printed with empty headers and
+% footers. \pkg{ekdosis} must be given control over every item of
+% information inserted in these areas beforehand.
+%
+% \DescribeMacro{\ekdprintmark}
+% \cs{ekdprintmark}\marg{selector}\marg{signpost} The signposts
+% printed in headers and footers must be passed as second argument of
+% \cs{ekdprintmark} so that \pkg{ekdosis} can remove them on pages
+% where printing them is not desirable. \meta{selector} refers to
+% three symbolic letters where the first can be either |H| or
+% |F|\===for \underLine{h}eader or \underLine{f}ooter\===, the second
+% |E| or |O|\===for \underLine{o}dd or \underLine{e}ven\===and the
+% third |L|, |C| or |R|\===for \underLine{l}eft, \underLine{c}enter or
+% \underLine{r}ight. The example provided above would then read as

+          {\ekdprintmark{HOC}{Epidemiarum liber II, \ekdmark}}
+          {\ekdprintmark{HOR}{\thepage}}
+}
+% Apply the page style:
+\pagestyle{edition}

+% \iffalse

+% \fi
+%
+% \DescribeMacro{\ekdnohfmarks} Once all signposts are marked with
+% \cs{ekdprintmark}, \cs{ekdnohfmarks} can be used at any point of the
+% document with the same effect as the \LaTeX\ standard command
+% \cs{thispagestyle}|{empty}|.
+%
+% \DescribeMacro{\ekdresethfmarks} Finally, \cs{ekdresethfmarks} is
+% provided in rare cases when it is needed to reset headers and
+% footers to their original, viz.\ printable state.
