Synopsis

tertiary ::=

Attributes

Additional attributes:

  • sortas

Description

A tertiary element contains a third-level word or phrase in an indexterm. The text of a tertiary term is less significant than the primary and secondary terms for sorting and display purposes.

DocBook does not define any additional levels. You cannot use indexterms to construct indexes with more than three levels without extending the schema.

In indexterms, you can only have one primary, secondary, and tertiary term. If you want to index multiple tertiary terms for the same primary and secondary, you must repeat the primary and secondary in another indexterm. You cannot place several tertiarys in the same primary.

☝
Important

In DocBook 5.x, a primary may contain nested indexterm elements. This is unsupported and will be removed in DocBook V6.0.

Processing expectations

Suppressed. This element provides data for processing but is not rendered in the primary flow of text.
