Topic domains: Basic DITA

A DITA vocabulary domain defines a set of elements associated with a particular subject area or authoring requirement regardless of topic type. DITA incorporates three domains into the basic DITA content: typographic, utilities, and indexing. Other domains are incorporated into the DITA Technical Content and Learning and Training specializations.

The elements in a domain are defined in a domain module. A domain module can be integrated with a topic type to make the domain elements available within the topic type structure. The following domains are provided as part of basic DITA:
