Dscp and DscpOrAny TCs

Do Diffservers think that the following is wise and makes sense?

   docsSubMgtPktFilterDscpValue OBJECT-TYPE
       SYNTAX      Dscp
       MAX-ACCESS  read-create
       STATUS      current
       DESCRIPTION
           "The Differentiated Services Code Point (DSCP) value to match
            in the IP packet."
       DEFVAL { 0 }
       ::= { docsSubMgtPktFilterEntry 9 }

   docsSubMgtPktFilterDscpMask OBJECT-TYPE
       SYNTAX      Dscp
       MAX-ACCESS  read-create
       STATUS      current
       DESCRIPTION
           "The mask to apply against the DSCP value to be matched in
       the IP packet.  The default for both these objects taken together
       matches all DSCP values. A packet matches this filter if the
       following is true:
           AND (FilterDscpValue, FilterDscpMask) ==
           AND (Packet DSCP Value, FilterDscpMask)."
       DEFVAL { 0 }
       ::= { docsSubMgtPktFilterEntry 10 }

It is defined in draft-ietf-ipcdn-subscriber-mib-10.txt and I'd like
to hear comments from Diffserv experts.

Thanks,
Bert
