Hello all, I have been selected as the Applications Area Directorate co-reviewer for this draft (for background on appsdir, please see http://trac.tools.ietf.org/area/app/trac/wiki/ApplicationsAreaDirectorate ). Please resolve these comments along with any other Last Call comments you may receive. Please wait for direction from your document shepherd or AD before posting a new version of the draft. Document: draft-ietf-eai-popimap-downgrade-05 Title: Post-delivery Message Downgrading for Internationalized Email Messages Reviewer: Claudio Allocchio Review Date: April 30th 2012 IETF Last Call Date: n/a IESG Telechat Date: n/a Summary: This document is requires a major decision about updating/non updating RFC 5322 before it can go to publication. Once this is done, other minor changes are listed below and it can be published. Another issue to clarify/fix is its relationship with draft-ietf-eai-simpledowngrade-03 specification (and also in that document, of course, with respect to this one). Major Issues: 3. Updating RFC 5322 this is a big major issue in this specification. I do not believe that stating something like "It is anticipated that when existing implementations encounter a downgraded field from this set, many will tolerate the appearance of a group" is a possible thing into a Standards Track specification. Th "update" to RFC 5322 is a big major one, and cons should be carefully evaluated here, too. As the "Notes in Draf" itself states, there is an alternate, much safer mechamism which can be used, and convey the same information to the user. This isse must be clarified before this specification can be publisehd, and a decision taken. Minor Issues: there is not cross-reference at all with draft-ietf-eai-simpledowngrade-03! many implementers could ge confused about the releationship between these specifications. In the Summary this should be explicitly described and clearly stated. Security Considerations this section describes quite well the possible scenarios which this specification introduces (and can also be a good example for re-writing the same secrion in draft-ietf-eai-simpledowngrade-03); I'd just suggest a further review by the Security area folks, too. Just in case... Nits: 1.1 Problem statement I'd suggest removing "Discussions leading to this specification concluded that " and just start with "There are four...' 5.1.1 until 5.1.9 in the titles you use the defintions without the <...> surrounding them. e.g. 5.1.5 GROUP Downgrading. I'd suggest changing them all using the < and > ... e.g. 5.1.5 <GROUP> Downgrading. etc. IANA Considerartions: ... to be fixed with IANA before publication! All over the document (and expecially in the A.1 example): this document uses a different convetion than draft-ietf-eai-simpledowngrade-03 for non ASCII elements in addresses/fields. Please unify the used convetion with the other draft (whichever of the 2 convetion is better) before publication. Here you write "NON-ASCII-something..." there you just use UPPERCASE. ------------------------------------------------------------------------------ Claudio Allocchio G A R R Claudio.Allocchio@garr.it Senior Technical Officer tel: +39 040 3758523 Italian Academic and G=Claudio; S=Allocchio; fax: +39 040 3758565 Research Network P=garr; A=garr; C=it; PGP Key: http://www.cert.garr.it/PGP/keys.php3#ca
