Re: [mpls] [Gen-art] review: draft-ietf-mpls-extended-admin-group-05

Works for me.
So

" The EAG sub-TLV is used in addition to the Administrative Groups
when an operator wants to make more than 32 colors available for
advertisement in a network"

I had gone back and forth with Adrian on language to scope this to a
single LSDB, so as to avoid the discussion of signaling EAG desire in
RSVP or PCEP.  I don't want to add that sort of disclaimer here too,
as it makes the sentence clunky and unweildy.
