Hi Mach,

Thanks for your review.

> I have only one comment regarding to Section 5. IMHO, although it's informational, the description about the relationship between SAFI-1 and SAFI-4 routes should not belong to this document, it's a more common description that is not specific to this label binding process. I'd suggest to remove this section if there is no any other reasons.

Differing interpretations about the relationship between SAFI-1 and 
SAFI-4 are a very common source of interoperability problems among 
implementations of different vendors.  Thus I think it is very useful to 
document this issue and to call attention to some of the differing 
interpretations.  I think this document is an appropriate place for this 
information; even though this information is not about label binding, it 
is about the semantics of SAFI-4.
