Hello Adrian,

I agree with what you propose, apart from a small
editorial change, see in-line [hvh]

Cheers, Huub.

[hvh] recommendation G.7041 does not contain any VCAT/LCAS
mechanism (it is the GFP definition), G.7042 is the generic LCAS definition. PDH VCAT is defined in G.7043, SDH/SONET VCAT in G.707 and OTN VCAT in G.709.
G.7042, G.7043, G.707 and G.709 are referenced in draft-ietf-ccamp-gmpls-vcat-lcas-01
I propose to remove G.7041 or replace it by G.7043.
(yes, it is in the original SG15 liaison text, but it is not
necessary to repeat the typo)
