\section{DTD for the format of dictionaries} \label{ss:dtd_dics}

The description of its elements can be found in Section \ref{formatodics}.

\subsection{Modification of the DTD of dictionaries for lexical selection} \label{dixdtd}
The DTD for the format of dictionaries has been slightly modified so that dictionaries can be used in a system that has a lexical selection module. The change only affects the \texttt{<e>} element and is displayed next.
\begin{small} \begin{alltt}

<!– r: restriction LR: left-to-right, RL: right-to-left –> <!– lm: lemma –> <!– a: author –> <!– c: comment –> <!– i: ignore (’yes’) means ignore, otherwise it is not ignored) –> <!– slr: translation sense when translating from left to right –> <!– srl: translation sense when translating from right to left –> ...
