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.

Summary: ready with minor issues

The security considerations section seems mostly reasonable.  The
emergency services use case vaguely bothered me in ways I couldn't quite
articulate at first, but I think Alissa Cooper's ballot comment about
denying emergency services by manipulating these attributes captures
most of the essence.

I would add for that these new language tags, integrity seems to be a
stronger requirement than confidentiality, at least in the emergency
calling use case.

Best regards,
