<metadata>
The <metadata>
section of the <prolog>
contains
information about a topic such as audience and product information. Metadata can be used by
computational processes to select particular topics or to prepare search indexes or to
customize navigation. Elements inside of <metadata>
provide information
about the content and subject of a topic; <prolog>
elements outside of
<metadata>
provide lifecycle information for the content unit (such
as the author or copyright), which are unrelated to the subject.
