<para>If non-zero, number labels for <tag>chapter</tag>,
<tag>appendix</tag>, and other component elements are prefixed with
the label of the part element that contains them.  So you might see
Chapter II.3 instead of Chapter 3.  Also, the labels for formal
elements such as <tag>table</tag> and <tag>figure</tag> will include
the part label.  If there is no part element container, then no prefix
is generated.
</para>
<para>
This feature is most useful when the
<parameter>label.from.part</parameter> parameter is turned on.
In that case, there would be more than one <tag>chapter</tag>
<quote>1</quote>, and the extra part label prefix will identify
each chapter unambiguously.
