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.
