Keywords are rarely displayed to a reader. Usually, they are reserved for searching and retrieval purposes. If they are displayed, they may be displayed either inline or as a displayed block, depending on context.

Unlike SubjectTerms, which should be drawn from a controlled vocabulary, keywords may be chosen freely.


These elements contain Keyword: KeywordSet.


In some contexts, the following elements are allowed anywhere: BeginPage, IndexTerm.
