indexterm

An <indexterm> is an index entry. You can nest entries to create multi-level indexes. The content is not output as part of topic content, only as part of the index.

When DITA topics are output to XHTML, any indexterm elements in the <keywords> element are placed in the Web page metadata, in addition to becoming part of the generated index.
