<para>This parameter has a structured value. It is a table of space-delimited
path/value pairs. Each path identifies some element in the source document
using a restricted subset of XPath (only the implicit child axis, no wildcards,
no predicates). Paths can be either relative or absolute.</para>

<para>When processing a particular element, the stylesheets consult this table to
determine if a ToC (or LoT(s)) should be generated.</para>

<para>For example, consider the entry:</para>

<screen>book toc,figure</screen>

<para>This indicates that whenever a <tag>book</tag> is formatted, a
Table Of Contents and a List of Figures should be generated. Similarly,</para>

<screen>/chapter toc</screen>

<para>indicates that whenever a document <emphasis>that has a root
of</emphasis> <tag>chapter</tag> is formatted, a Table of
Contents should be generated. The entry <literal>chapter</literal> would match
all chapters, but <literal>/chapter</literal> matches only <tag>chapter</tag>
document elements.</para>

<para>Generally, the longest match wins. So, for example, if you want to distinguish
articles in books from articles in parts, you could use these two entries:</para>

<screen>book/article toc,figure
part/article toc</screen>

<para>Note that an article in a part can never match a <literal>book/article</literal>,
so if you want nothing to be generated for articles in parts, you can simply leave
that rule out.</para>

<para>If you want to leave the rule in, to make it explicit that you're turning
something off, use the value <quote>nop</quote>. For example, the following
entry disables ToCs and LoTs for articles:</para>

<screen>article nop</screen>

<para>Do not simply leave the word <quote>article</quote> in the file
without a matching value. That'd be just begging the silly little
path/value parser to get confused.</para>

<para>Section ToCs are further controlled by the
<parameter>generate.section.toc.level</parameter> parameter.
For a given section level to have a ToC, it must have both an entry in 
<parameter>generate.toc</parameter> and be within the range enabled by
<parameter>generate.section.toc.level</parameter>.</para>
