\maketitle

The package as loaded causes section numbers to be output with a dot
after them.

The command \cmd{\sectiondot}\marg{level} will make `\meta{level}' sections also be
output with a dot after them -- an example of use would be:
%
\begin{lstlisting}
\sectiondot{subsection}
\end{lstlisting}

The command \cmd{\sectionpunct}\marg{level}\marg{punctuation} gives finer
control. Examples of use would be
%
\begin{lstlisting}
\sectionpunct{section}{. } % \sectiondot places a \quad after the
                               % dot, which may look excessive
\sectionpunct{section}{\quad} % restores default latex behaviour
\end{lstlisting}

Other eccentricities of numbering could be coded by those with
stronger stomachs, by defining the appropriate
%
\begin{lstlisting}
\csname @seccntfmt@$\meta{level}$\endcsname
\end{lstlisting}
%
macro which will take one argument, when invoked: the `\meta{level}' name.

If \verb|\DocumentMetadata| is used, section headings are
implemented via \LaTeX\ templates which offer much more flexible
customisation, and this package is not recommended for new documents.
However, a basic set of \verb|\EditInstance| declarations are included
in this package so that the basic functionality still works in
combination with \verb|\DocumentMetadata|.
