source

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 attribute is used to reference a description of the resource. It is implementation-dependent what it means when the element has both content and an href attribute value.

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