JL,

I have a couple of comments/suggestions.

1.	The draft says that currently GMPLS does not have a
mechanism to provision virtual FAs. I don?t think this
is correct ? I believe we could use the same mechanism
as was suggested in
draft-ietf-ccamp-gmpls-recovery-e2e-signaling (section
9.3) for signaling of Secondary LSPs
2.	I agree that we need TE link adaptation
capabilities to be advertised along with other TE link
attributes such as switching capabilities, protection
capabilities, etc. I suggest also adding TE link
termination capabilities to this list, i.e. decoupling
of these capabilities from adaptation capabilities: 
to terminate LSP in a particular layer and to adopt
into it LSPs of one or more higher layers are separate
resources and could be considered separately in the
inter-layer path computations;
3.	Everything that is said about regions, region
boundaries, etc. is also applicable for layers
contained within regions. I suggest to do what we have
already done in the PCE WG documents and
presentations: replace word region with word layer
everywhere apart from where signaling specific aspects
are discussed.

Thanks,
Igor
