+% \section[Lacunae]{\newfeature[v1.5]Lacunae}
+% \label{sec:lacunae}
+% The term \enquote{lacuna} is used here to indicate a series of words
+% or phrases that are missing from one or more witnesses in the
+% manuscript tradition. When the lacuna is limited to just a few
+% words, it may fill an entire entry of the apparatus criticus,
+% especially when the other witnesses do not provide variants on this
+% span of text.
+%
+% On the other hand, when the lacuna is longer, or includes variants,
+% or crosses a verse, paragraph or section boundary, it is usually not
+% desirable to break it into pieces. The recommended method of
+% encoding is therefore to record explicitly where the lacuna begins
+% and where it ends. However, in well-written apparatus criticus,
+% these two items of information must be provided only in the first
+% entry. Moreover, the line numbering of this entry and the
+% abbreviated lemma must make clear where the lacuna ends. As a
+% consequence, the apparatus in print is silent at the place where the
+% lacuna ends, unlike the \texttt{TEI xml} code which must be explicit
+% at both places.
+%
+% \DescribeMacro{\lacunaStart}\DescribeMacro{\lacunaEnd}
+% \cs{lacunaStart}\oarg{opt} and \cs{lacunaEnd}\oarg{opt} are used in
+% the mandatory argument of the \cs{rdg} command to indicate the
+% beginning and the end of the lacuna. The optional argument of these
+% commands can be used to specify which witnesses are affected by the
+% lacuna, as follows:---\\
+% \DescribeOption{wit} |wit|$=$\meta{csv list of witnesses}\\
+% This option is described above \vpageref{ref:lem-wit}. Of course, it
+% is unnecessary to use it in the case where only one witness in
+% involved in the variant reading that supply the information on the
+% lacuna.
+%
+% \DescribeMacro{\ilabel} \phts\label{ref:ilabel-cmd}
+% \cs{ilabel}\marg{indexed label} is used to recall the indexed label
+% set by means of the |ilabel| optional argument of the \cs{lem}
+% command as described above \vpageref{ref:ilabel-opt}. This command
+% is used to compute the line number where the lacuna ends and must be
+% inserted precisely at this place, supposedly outside the group
+% formed by the \cs{app} command used to print the information on the
+% lacuna in the apparatus criticus.
+%
+% This technique is demonstrated by the following example taken from
+% Cicero's \emph{Letters to Atticus}, VII,
+% 9.4:\footnote{\cite[121.13--15]{CiceroAtt}. English translation:
+% \cite[51]{CiceroAttTr}.}---

+% \begin{remarks}
+% \item At line~\lnref{ln:lac:ilabel:opt}, from the |ilabel| optional
+%   argument, \pkg{ekdosis} knows that the span of text affected by
+%   the lacuna does not end after \emph{sed}, but after \emph{legis}
+%   (l.~\lnref{ln:lac:ilabel:cmd}), at the place where the indexed label
+%   is recalled by \cs{ilabel}. So line numbers are computed
+%   accordingly in the apparatus criticus.
+% \item The starting and ending points of the lacuna from which the
+%   \sg{Ω} family suffers have been marked by \cs{lacunaStart} and
+%   \cs{lacunaEnd} respectively (ll.~\lnref{ln:lac:lstart} and
+%   \lnref{ln:lac:lend}).
+% \item Line~\lnref{ln:lac:lend} shows that \emph{legis}
+%   (l.~\lnref{ln:lac:ilabel:cmd}) does not appear in the \sg{Ω}
+%   family. This is where the lacuna ends. Furthermore, as no other
+%   witnesses are mentioned in the \cs{rdg} command
+%   (l.~\lnref{ln:lac:lend}), using the |wit| optional argument of
+%   \cs{lacunaEnd} would introduce an unnecessary redundancy.
