I changed the subject line and fixed the proposed TC. So here is where
I think we are. I have also reduced the CC list and I have added the
diffserv mailing list since diffserv folks should be in the loop I
think.

  FlowId TECTUAL-CONVENTION
      DISPLAY-HINT "d"
      STATUS       current
      DESCRIPTION 
	"The flow identifier in an IPv6 header that may be used to
	 discriminate traffic flows."
      REFERENCE
	"RFC 2460"
      SYNTAX       Integer32 (0..1048575)

  FlowIdOrAny TECTUAL-CONVENTION
      DISPLAY-HINT "d"
      STATUS       current
      DESCRIPTION 
	"The flow identifier in an IPv6 header that may be used to
	 discriminate traffic flows. The value of -1 is used to
	 indicate a wildcard, i.e. any value."
      REFERENCE
	"RFC 2460"
      SYNTAX       Integer32 (-1 | 0..1048575)

Open issues:

- Is the flow identifier the same as the flow label? I guess so. If
  this is true, then we should probably use the TC names FlowLabel
  and FlowLableOrAny and also change the wordings in the description
  clause.

- The name of the MIB modules which will contain these definitions.

- Since Fred kind of said that the diffServMultiFieldClfrFlowId
  object should have had a wildcard, can we agree that this is 
  actually a bug in RFC 3289 which will be fixed by using FlowIdOrAny
  in the next revision of the DIFFSERV-MIB?
