Looks fine. One item I would like to see changed (or at least discussed)

I have a problem with chapter3 – Para6 – Point 1 :

EXISTING:

If T's destination IP address is from the same address family as

the computing OSPF instance, then the tunnel must have been

signaled based on MPLS TE information propagated in the same OSPF

instance.  Process the tunnel as per [RFC3630<https://tools.ietf.org/html/rfc3630>] or [RFC5329<https://tools.ietf.org/html/rfc5329>].

PROPOSED:

If T's destination IP address is from the same address family as

the computing OSPF instance, then process the tunnel as per [RFC3630<https://tools.ietf.org/html/rfc3630>] or [RFC5329<https://tools.ietf.org/html/rfc5329>].

MOTIVATION:
I do not understand why to restrict the tunnel to be signaled with only info from same OSPF instance. If there is tunnel available (different instance, or even other routing protocol), it should be able to be used.
