Kwok, will this result in a change to the diffserv PIB?
If so we will have to do a check with this WG whether anyone
objects to the change, since the PIB passed Last Call a long
time ago.

If it introduces a dependency on a new draft, the PIB RFC will
be blocked (again). So maybe you will have to paste in the TCs.

Please tell us the exact changes you plan to the PIB.

Thanks
    Brian
