<index-base>
The <index-base> element allows indexing extensions to be added by
specializing this element.
The <index-base> element can only exist as a child of an
<indexterm> element. This characteristic makes it the appropriate
element to specialize to add indexing extensions. For example, the <index-see>, <index-see-also>, and <index-sort-as> elements only make
sense as children of <indexterm> and so are specializations of
<index-base>. Those elements are all part of the indexing domain.
On its own, <index-base> has no meaning. Processors should ignore this
element and its content if encountered in its unspecialized form.
