Vito,

Please reference the diffserv-pib-03 draft, specifically Section 9.

Subect Category Considerations

The numbering space used for the DiffServ PIB, as indicated by the
SUBJECT-CATEGORIES clause, will be assigned by the Internet Assigned
Numbers Authority (IANA).  Notice the numbering space used by SUBJECT-
CATEGORIES maps to the Client Type numbering space in [COPS-PR].  This
relationship is detailed in section 7.1 of [SPPI].  Due to the fact that
Client Type value of 1 has already been used by [COPS-RSVP], the
numbering space for SUBJECT-CATEGORIES will need to start with the value
of 2.

COPS-PR can support multiple COPS Client-Type values.  The Client-Type
specified for QoS is 2.

Regards,

Tina Iliff

		I have a doubt about this: reading the entire COPS-PR RFC
and especially 
		the "IANA Consideration" section we find that:

		9. IANA Considerations

		   COPS for Policy Provisioning follows the same IANA
considerations for
		   COPS objects as the base COPS protocol [COPS].  COPS-PR
has defined
		   one additional Decision Flag value of 0x02, extending the
COPS base
		   protocol only by this one value.  No new COPS Client-
Types are
		   defined by this document.

		The last sentence explicitly says that no new Client-type
are defined, so:
		Q1: what document specifies the client-type value of 2 ?
		Q2: if not specified, what Client-type COPS-PR clients have
to use?
