The <keywords> element contains a list of terms from a controlled or uncontrolled subject vocabulary that applies to the topic or map. The keywords may be used by a search engine. The keywords are marked up using the <indexterm> and/or <keyword> elements.

All <keyword> and/or <indexterm> elements in the <keywords> element are considered part of the topic's metadata and should be reflected in the output as appropriate for the output medium.
Note: While the <keyword> element may be used inline, the <keywords> element is not an inline element. The <keywords> element only appears in the <topicmeta> or <prolog>, and is used to specify keywords that apply to the topic.


Note: These models represent only the default document types distributed by OASIS. Actual content models will differ with each new document type.
