Deprecated Content in DITA Documents

DITA encourages writing of content as modular topics. Content is devided into small, self-contained topics that can be reused in different deliverables and single-sourced in a variety of ways. This approach is opposed to writing long "book-oriented" files such as Docbook. DITA topic-oriented approach emphasizes modularity and reuse of topics as concise units of information. Also, fragments of content within topics can be reused.

The use of XInclude and entities is deprecated in DITA. Instead, use the DITA-specific conref mechanism to transclude the content of a target, or use some other type of a reference.

Referencing is an effective means of content reuse in DITA. Content reuse is available at different levels (elements, topics, maps) by means of different types of references.
