<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
resolved.</para>
