Summary: This document is nearly ready for publication as a Proposed 
Standard RFC.  I believe there is one major issue that is easily addressed.

Major issues:
     I may have simply missed this reviewing the document, but as far as 
I can tell there is no specification of the relationship between the 
MT-IDs in this document and the MT-IDs used elsewhere.  Yes, I can take 
a guess at the intent.  But is it stated somewhere that these are the 
same IDs negotiated in the relevant IGP?  Or is there some other intent?

Minor issues:

Nits/editorial comments:
     I find it odd that the MT-ID follows the IP prefix in the various 
formats.  Yes, the computer can parse both.  But since we tend to think 
in Network byte order, I expect more significant information (MT-ID) to 
occur before less significant information (IP prefix within topology.)
