This is an issue for the TAG.

RFC 2396, "4.1. Fragment Identifier" says as follows:

   The semantics of a fragment identifier is a property of the data
   resulting from a retrieval action, regardless of the type of URI used
   in the reference.  Therefore, the format and interpretation of
   fragment identifiers is dependent on the media type [RFC2046] of the
   retrieval result.  ...

It is defined to be dependent on the media type.  If RFC 3023 gets
updated and adopted XPointer, then if you serve an XHTML 2 document
as 'application/xml', whatever fragment identifier syntax allowed for
'application/xml' may be used for that document - though, currently
there's no defined fragment identifier syntax in RFC 3023.

We thought that's a disaster, so "[u]ntil [XMLMIME] gets updated",
the 'application/xhtml+xml' media type uses 'id' attribute value.
Once RFC 3023 gets updated, RFC 3236 will also be updated to adopt
whatever 'application/xml' adopted.

No.  We are waiting XPointer to advance to more mature stage, and
relevant media type registrations get updated.
