Assuming the OP is referring to RFC 3630, I suppose you wouldn't hear
much about IS-IS either in this regard, since the TE extensions to IS-IS
and OSPF are not the final product. The final product would be MPLS-TE
itself. IS-IS and OSPF are just a ubiquitous way to get the TE
information across the backbone.
