<para>If <parameter>label.from.part</parameter> is non-zero, then
  numbering of components — <tag>preface</tag>,
  <tag>chapter</tag>, <tag>appendix</tag>, and
  <tag>reference</tag> (when <tag>reference</tag> occurs at the
  component level) — is re-started within each
  <tag>part</tag>.</para>
<para>If <parameter>label.from.part</parameter> is zero (the
  default), numbering of components is <emphasis>not</emphasis>
  re-started within each <tag>part</tag>; instead, components are
  numbered sequentially throughout each <tag>book</tag>,
  regardless of whether or not they occur within <tag>part</tag>
  instances.</para>
