<para>
<sgmltag>Tertiary</sgmltag> contains a third-level word or phrase in an
<sgmltag>IndexTerm</sgmltag>.  The text of a <sgmltag>Tertiary</sgmltag> term
is less significant than the <sgmltag>Primary</sgmltag> and
<sgmltag>Secondary</sgmltag> terms for sorting and display purposes.
</para>

<para>
DocBook does not define any additional levels. You cannot use
<sgmltag>IndexTerm</sgmltag>s to construct indexes with more than three
levels without extending the &DTD;.
</para>

<para>
In <sgmltag>IndexTerm</sgmltag>s, you can only have one primary,
secondary, and tertiary term. If you want to index multiple
tertiary terms for the same primary and secondary, you must
repeat the primary and secondary in another
<sgmltag>IndexTerm</sgmltag>. You cannot place several
<sgmltag>Tertiary</sgmltag>s in the same primary.
