I said effectively the same thing at the mike in the nvo3 meeting - this draft is not using diffserv - it's inventing something new, and that's a bad idea.

This is not in any way compatible with RFC 2474, which also made the relevant part of RFC 791 obsolete. If you want to be compatible with RFC 2474 you should not specify the bits at all - just say that they are exactly as defined in RFC 2474 and the various PHB definitions that have been published. If you want to be compatible with IEEE 802.1p that is a different matter, but you cannot mix the two up in this way.
