Ok. Good. To be concrete, here's what I think I'd like 3023 to say:

1. +xml media types SHOULD use application/xml semantics for fragment
   identifiers.

2. Media type registrations for +xml media types should explicitly
   acknowledge that they use 3023 fragment identifier semantics

3. Unless a media type registration for a +xml media type explicitly
   says otherwise, generic XML processors are licensed to attempt to
   resolve fragment identifiers using the application/xml
   semantics.

                                        Be seeing you,
                                          norm
