Authors/WG,
	I notice that the above drafts don't quite follow how
upstream/downstream label ROs are identified in RFC3473, i.e. separate
objects with direction identified using the U-bit.

Is there any objection to using this same identification approach in
both drafts?
(Certainly there's a tradeoff of consistency vs optimal
bidirection/unidirectional representation, but I think consistency wins
with so little difference in this case.)

Thanks,
Lou
