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.
