41.7 Specializing or modifying DITA topic types

To include custom specialized topic types or maps in your DITA project, you must provide a separate content-model configuration file for each new topic type or modified map or bookmap DTD. You can derive a new type from any of the built-in topic types topic, concept, task, reference, map, or glossary (DITA 1.1 only), or from another specialized type for which you provide a DTD.

To produce the constraints supported by DITA 1.2, you can run utility program dtd2ini (see §41.2.2 Generating a content model from a DTD) on a local document type shell, and reference the result in your project configuration chain.
