Support draft-comment in more places.
Support draft-comment in locations that need it but do not allow it today.
Users often wish to insert draft-comments in locations that do not allow it. Two specific examples are inside <body> and inside <shortdesc>. Users have requested each of these locations; based on other DITA content models it seems logical for draft-comment to appear here.
It likewise seems logical to allow draft-comment inside <conbody> which is nearly identical to <body>, so that is also part of this proposal.
Update to DTDs and Schemas.
Reduce user confusion, allow draft comments closer to the item that needs commenting.
Updates to the contains/contained by sections of body, shortdesc, conbody, and draft-comment.
