Description
A subjectset
is a container for a set of
subject
s. All of the subject
s
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
subjectset
s in different parts of a document or
between a subjectset
and the
subjectset
s of enclosing parts of the document.
