subjectset — A set of terms describing the subject matter of a document
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.
May be formatted inline or as a displayed block, depending on context. Subjects are rarely displayed to a reader. Usually, they are reserved for searching and retrieval purposes.
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.
These elements contain subjectset: biblioentry, bibliomixed, bibliomset, biblioset, info (db.info), info (db.titleforbidden.info), info (db.titleonly.info), info (db.titleonlyreq.info), info (db.titlereq.info).
