     Insert plugins are used to implement functions that are invoked by
     <link linkend="language.function.insert"><varname>{insert}</varname></link>
     tags in the template.

    <para>
     The first parameter to the function is an associative array of
     attributes passed to the insert.
    </para>
    <para>
     The insert function is supposed to return the result which will be
     substituted in place of the <varname>{insert}</varname> tag in the
     template.
