But please note that this document, unlike RFC 5335, introduced UTF-8 additions to *base* RFC 5322 productions. This means that <addr-spec> will be defined as follows now: > addr-spec = local-part "@" domain > local-part = dot-atom / quoted-string / obs-local-part > domain = dot-atom / domain-literal / obs-domain > domain-literal = [CFWS] "[" *([FWS] dtext) [FWS] "]" [CFWS] > dtext = %d33-90 / ; Printable US-ASCII > %d94-126 / ; characters not including > obs-dtext ; "[", "]", or "\" > dtext =/ UTF8-non-ascii ; from 5335bis > dot-atom = [CFWS] dot-atom-text [CFWS] > dot-atom-text = 1*atext *("." 1*atext) > atext =/ UTF8-non-ascii ; from 5335bis So everything you will have to do is to have a note on 'acct' RI being possible to carry UTF8 characters and therefore being possibly IRIs. > Link relation types might be names like “copyright” or they might be > URIs.

I've already pointed to http://tools.ietf.org/html/draft-ietf-vcarddav-social-networks-00, which VCARDDAV WG works on, and so you may try to introduce some similar property for Webfinger IDs. (You see, vCards may not carry all the variety of information, though some people actually think in other way, and thus it would be a good idea to provide a means of accessing some additional info.) > For comments on particular sections, I’ve added notes to each one to > revise them as you suggest: they’re all good suggestions. > Yes, thanks as well. > I would very much like to make this a WG item, of course, but none of > the authors will be present at this IETF meeting.
