Last Call Review of draft-ietf-idnabis-defs-
review-ietf-idnabis-defs-secdir-lc-hoffman-2009-10-22-00

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. Feel free to forward to any appropriate forum.

This document is one of a series of four that make up the revised IDNA protocol
(draft-ietf-idnabis-defs, -tables, -protocol, -bidi). The four document are
intertwined, so the security considerations for all should be considered at the
same time. Having said that, I find no significant issues with the security
considerations in any of the four documents, including this one. Given the
messy nature of both internationalization and designing user input mechanisms,
these documents do the best that they can, and are not noticeably worse (and
are hopefully better) than the previous IDNA protocol.
