I have reviewed this document as part of the security directorate's 
ongoing effort to review all IETF documents being processed by the 
IESG.  These comments were written primarily for the benefit of the 
security area directors.  Document editors and WG chairs should treat 
these comments just like any other last call comments.

For some reason I've got the assignment to re-review this document past its deadline
(I've got the assignment today, 20 February, and the indicated deadline for the review is 18 February,
so I'm not sure whether this review is still useful).

Anyway, the document has received some changes from -02 version which I reviewed last time.
In particular, Security Considerations section is enhanced with the text describing
a potential for a confusion about the proper unit to use. While I'm not sure it's really
a security condideration and not an interoperability consideration, I agree that
there are no additional threats from security point of view.

And my concern about improper use of normative language is resolved.
