RE: TIFF-FX: technical changes since RFC 2301

Perhaps it would be useful to clarify this also
in draft-ietf-fax-service-v2-05.txt, section 4:

OLD

   A sender SHOULD NOT use TIFF fields and values beyond
   the minimum subset....

NEW

   A sender SHOULD NOT use a MIME type other than
   'image/tiff' or TIFF fields and values beyond
   the minimum subset...

because otherwise interoperability of the baseline
RFC 2305 protocol might be disturbed by this change
to the referenced document; the old reference [5]
to RFC 2301 only had one MIME type, and so it wasn't
previously necessary to say this.
