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.
Small impact.
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.
