A question for you:

If I understand correctly, the motivation for this draft is to allow LDP 
to be the single mechanism to distribute reachability rather than 
counting on a 2547bis-like mechanism.
The overall approach of carrying the External FEC in the FEC TLV 
guarantees that these label mappings will not be propagated in a network 
of mixed LDP implementations.  Have you considered this situation?
