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.
Processing expectations
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.
