<para>Specifies that if an empty <tag>toc</tag> element is found in a
source document, an automated TOC is generated at this point in the
document.
<note>
  <para>Depending on what the value of the
  <parameter>generate.toc</parameter> parameter is, setting this
  parameter to <literal>1</literal> could result in generation of
  duplicate automated TOCs. So the
  <parameter>process.empty.source.toc</parameter> is primarily useful
  as an "override": by placing an empty <tag>toc</tag> in your
  document and setting this parameter to <literal>1</literal>, you can
  force a TOC to be generated even if <tag>generate.toc</tag>
  says not to.</para>
