RE: [Diffserv] Re: FlowId and FlowIdOrAny

OK, so if I understand you correctly, then the newly proposed
TCs would also be useable for the Intserv MIB when they do
a revision, right? And again that can then be considered
a bug fix. 

So we now have a conflict in that if we make it Integer32, 
then diffserv MIB needs to deprecate and create a new object
If we make it Unsigned32, then Intserv MIB needs to deprecate
and create a new object.

It then seems to me that making it Integer32 as suggested by
Juergen then makes the most sense, since that seems to be
then more consistent with how we have done this at other
places (that is, used a -1 value to mean any).

Comments?

Thanks,
Bert
