KeywordSet ::= (Keyword+)
Both the start- and end-tags are required for this element.
A set of keywords, provided by the author, editor, publisher, and so on, can be stored in the document meta-information in a KeywordSet.
Keywords can form an important part of an automated indexing or searching strategy for a collection of documents.
May be formatted inline or as a displayed block, depending on context. Keywords are rarely displayed to a reader. Usually, they are reserved for searching and retrieval purposes.
Unlike SubjectTerms, which should be drawn from a controlled vocabulary, keywords may be chosen freely.
Although more than one KeywordSet may appear in the meta-information for a document, neither a relationship nor a specific facility for constructing a relationship is defined by DocBook.
These elements contain KeywordSet: ArtHeader, BookInfo, DocInfo, ObjectInfo, RefSect1Info, RefSect2Info, RefSect3Info, RefSynopsisDivInfo, Sect1Info, Sect2Info, Sect3Info, Sect4Info, Sect5Info, SectionInfo, SetInfo.
