Document: draft-ietf-eai-rfc5337bis-dsn-01.txt
Title: Internationalized Delivery Status and Disposition Notifications
Reviewer: Ted Hardie
Review Date: December 15, 2010


Summary: Reviewers were asked to look specifically at the ABNF; it
appears to me correct and the output from abnfgen seemed sensible.
Eliot and Dave Crocker have already discussed the citation issue.
There are two other issues which I feel should be resolved.

Major Issues: The document says:

NOTE: The only issue for which there is (as yet) no consensus yet is
   whether to change the name of the Address Type from "UTF-8" to
   something different, such as "UTF8", to reflect the fact that the
   "<addr <addr>>" address syntax is no longer permitted.

Reviewing the mailing list there appeared to be one participant advocating
change (SM) and one "not an exciting question" (Shawn Steele) and one
noting a problem with changing it (Martin Dürst).  5335bis in the
current version
still calls this UTF-8; I believe that should govern this spec's usage and
this note should be removed.  A note to the RFC Editor to update this document
if the nomenclature changes in the normative reference should do this;
if not, then I believe
that the IESG can permit a change by later adding a new RFC Editor
note while it is
in queue.

Minor Issues:

The document says:

   The ability to encode characters with the EmbeddedUnicodeChar
   encodings should be viewed as a transitional mechanism.  It is hoped
   that as systems lacking support for UTF8SMTP become less common over
   time, these encodings can eventually be phased out.

Transitional mechanisms generally live a long, long time, and this one seems
likely to me to live at least to the end of my career.  I would
personally suggest
striking this text, but it does no harm if left in.

Nits:
Chris Newman's address in the draft appears to be old.
