Bernhard has produced an excellent  page on the issue wiki
http://www.w3.org/community/openannotation/wiki/Textual_Bodies. I
would urge that any discussions continue there. The "history" tab on
that page makes it easy to find out what is evolving, and the  "watch"
tab provides email notifications of changes.
