Index elements

The content of <indexterm> elements provides the text for the entries in a generated index. <indexterm> elements can be nested to create secondary and tertiary index entries.

The following elements contain information that processors use to generate indexes.

<indexterm>

Instructs a processor to generate an index entry. The @start and @end attributes on the <indexterm> element can specify index ranges.

<index-see>

Instructs a processor to generate a see reference. See references direct a reader to the preferred term.

<index-see-also>

Instructs a processor to generate a see also reference. See also references direct a reader to an alternate index entry for additional information.

How the index elements are combined, the location of <indexterm> elements, and the hierarchy of the DITA maps all effect how the index elements are processed and the resulting generated index entries.
