Darwin Information Typing Architecture (DITA) Version 1.3 Part 1: Base Edition

OASIS DITA Technical Committee

The source element identifies a resource from which the present topic is derived, either completely or in part.

The source element contains a description of the resource. Alternatively, the href or keyref attributes can be used to reference a description of the resource. It is implementation-dependent what it means when the element has both content and an attribute-based reference to another resource.

This element is equivalent to the Source element in Dublin Core.
