prolog

The <prolog> element contains information about the topic as an whole (for example, author information or subject category) that is either entered by the author or machine-maintained. Much of the metadata inside the <prolog> will not be displayed with the topic on output, but may be used by processes that generate search indexes or customize navigation.
