<para>
This parameter allows you to control the punctuation of certain
types of generated cross reference text.
When cross reference text is generated for an 
<tag class="element">xref</tag> or 
<tag class="element">olink</tag> element
using an <tag class="attribute">xrefstyle</tag> attribute
that makes use of the <literal>select:</literal> feature,
and the selected components include both label and title,
then the value of this parameter is inserted between
label and title in the output.
