-<para>If <parameter>rootid</parameter> is not empty, it must be the
-value of an ID that occurs in the document being formatted. The entire
-document will be loaded and parsed, but formatting will begin at the
-element identified, rather than at the root. For example, this allows
-you to process only <tag>chapter</tag> 4 of a <tag>book</tag>.</para>
-<para>Because the entire document is available to the processor, automatic
-numbering, cross references, and other dependencies are correctly
