Description

A SubjectSet is a container for a set of Subjects. All of the Subjects within a SubjectSet should come from the same controlled vocabulary.

A document can be described using terms from more than one controlled vocabulary. In order to do this, you should use the Scheme attribute to distinguish between controlled vocabularies.

DocBook does not specify a relationship between SubjectSets in different parts of a document or between a SubjectSet and the SubjectSets of enclosing parts of the document.
