Last Call Review of draft-ietf-dmm-4283mnids-04

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.

This document is ready with nits.

I was pleased that the security considerations does discuss some privacy
issues.  I think it would help to emphasize that identifiers can be
trackable since many of the IDs in the draft are long lived.  The section
does mention it, this suggestion is just for emphasis.

First sentence of second paragraph of security considerations.

"Some identifiers (e.g., IMSI) are considered to be private information and
some are long lived allowing for tracking of an individual or device."

Cheers,

Joe
