Container element for one set of keywords (such as <kwd>s, <nested-kwd>s, or <compound-kwd>s) used to describe a document.
Related Essay: For a discussion on the use of <kwd-group>, see Keywords.
Usage: A document may take multiple sets of keywords, with the @kwd-group-type, @specific-use, or @xml:lang attributes used to discriminate between them. The <kwd> element does not take the @xml:lang attribute; that is reserved for the <kwd-group>. This means that keywords must be sorted by language and entered in language groups.
The @kwd-group-type attribute most commonly names the source of the keywords, such as “MESH”, “ISO-463”, or “author-generated”. But it is also appropriate to use @kwd-group-type to record the type of keywords, for example, “hierarchical” for keywords that are grouped into a hierarchy, “abbreviations” for keywords that contain an abbreviation and its expansion, or “code” for keywords that contain a code and its text but where the source of the codes is unknown.
