I'm all in favor of the OAM label, but I share the concern that "giving away" a
label to the ITU isn't the best use of the small reserved label space.  I would
like to see an MPLS OAM label defined.  But the application of the label should
not be restricted to the Y.1711 proposal.  E.g., HVPLS OAM proposes to use an
OAM label.  We'd like to be able to use the MPLS OAM label without having to
exchange OAM FECs as proposed in that draft.

If we allow the use of a single label for all OAM applications that want to use
it, we now have the next issue of how do we demux to the different apps that
want to use this label?
