Bookmap metadata elements

The Bookmap specialization of ditamap supports standard book production for collections of DITA topics. This section contains the metadata elements used by bookmap to store book related metadata.

Note: The OASIS document type for the bookmap specialization includes the xNAL domain specialization for describing the author or authors of a document. All elements that appear in that domain (the authorinformation element and all of its descendants) are described in the xNAL domain section, rather than in this bookmap metadata section.
