## keywordset

keywordset — A set of keywords describing the content of a document.

keywordset ::=

## Description

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.

### Processing expectations

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 `subjectterm`s, 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.

Additionally, no relationship is defined between the `keywordset`s of a document component and the `keywordset`s of its parents or children.

### Parents
