The XHTML 2 Working Group is updating the XHTMLMIME document to reflect 
current best practices ala the ancient Appendix C to which you refer.  
The working group definitely recommends doing the type of content 
negotiation you are attempting to do.  You can see all XHTML 2 Working 
group documents under development, including a draft that is unapproved 
and still needs lots of work at http://www.w3.org/MarkUp/Drafts
