This draft specifies a SMTP extension.  The IANA Considerations does 
not mention registration in the the SMTP Service Extensions 
registry.  There should also be an indication about the extension 
being valid for the submit port.  The issue of referencing STANAG 
4406 was resolved by the IESG last year (see RFC 6477).

This draft also defines the MT-Priority header field.  It is quite 
unusual for a SMTP extension specification to define a mail header 
field.  If I had an reservations about this draft, it would be on 
architectural grounds.  The draft tries really hard to transfer 
priority information over the Internet and in a foreign 
environment.  Although the draft is well-written and can be 
implemented, I have doubts about whether it will achieve its 
objective.  I unfortunately cannot support the publication of this 
draft as a Proposed Standard.
