+% \subsection{Inserting Code in the \texttt{TEI xml} Ouput File}
+% \label{sec:inserting-code-tei}
+% It may be needed to insert code in the \texttt{TEI xml} output file
+% only, for example when clear enough information is written in the
+% apparatus criticus by means of such optional arguments as |pre|,
+% |post|, |prewit| or |postwit| that are not processed for \texttt{TEI
+% xml} ouput.\footnote{See above \vref{sec:single-text-editing}.}
+%
+% \DescribeMacro{\teidirect} \newfeature[v1.3] \cs{teidirect}\oarg{xml
+% attributes}\marg{xml element}\marg{code}\\
+% Two mandatory arguments are expected by \cs{teidirect}, namely the
+% \texttt{TEI xml} element followed by the contents to be found in the
+% ouput file between the opening and closing tags. Additionally,
+% attribute-value pairs to be found inside the start-tag of the
+% element can be specified in the optional argument of the command. An
+% example follows:

+% \begin{remarks}
+% \item |GalE1.M.Q| (l.~11) has been defined as a shorthand to denote
+%   the agreement of two otherwise defined manuscripts by means of
+%   \cs{DeclareWitness}: |GalE1.M| and |GalE1.Q|. (See ll.~2--6.)
+% \item The |postwit| optional argument has been used to further
+%   specify the location where this variant reading can be found in
+%   the critical edition of Galen's Commentary on Hippocrates'
+%   \emph{Epidemics}, Book~1 (l.~11). But as the effect of |postwit|
+%   is limited to the PDF output, \cs{teidirect} has been used to
+%   convey this item of information to the \texttt{TEI xml} ouput file
+%   (l.~12).
