For the resource [1] referenced by the URI [1] of the URI-reference [1] 
to have media type [2] "application/xml" or "text/xml".

Section 4.1. Fragment Identifier of [1] says:

   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.  

[1] http://www.ietf.org/rfc/rfc2396.txt contains definitions
of and/or pointers to definitions of each term.

No.
