Anoop,

Thanks again, we'll hold these for the next update. BTW, If we add a
reference to draft-ietf-mpls-sfc, then it may also be useful to add a
reference to draft-ietf-mpls-sfc-encapsulation in draft-ietf-mpls-sfc as
well. Since that's already gone to the IESG, that'll have to be an IETF LC
comment.

Cheers,
Andy
