<para>If 1, the stylesheets use the <function>id()</function> function
to find the targets of cross reference elements. This is more
efficient, but only works if your XSLT processor implements the
<function>id()</function> function, naturally.</para>
<para>THIS PARAMETER IS NOT SUPPORTED. IT IS ALWAYS ASSUMED TO BE 1.
SEE xref.xsl IF YOU NEED TO TURN IT OFF.</para>
