Hi,

I've started IETF LC on the document, as my comments are really minor:

1) I am not sure that deleted IANA registry descriptions (when compared 
to RFC 7601) is the best way, considering that this document obsoletes 
RFC 7601. I think it would be better to just keep the text and add a 
sentence saying that it is unchanged from RFC 7601. But I am happy to 
hear what IESG has to say about this.

2) The following took really long time to verify for correctness:

Section 2.5 says about authserv-id:

   Note that in an EAI-formatted message, this identifier may be
         expressed in UTF-8.

So I decided to check whether this statement is actually true.
authserv-id is defined in Section 2.2 as:

   authserv-id = value

   "value" is as defined in Section 5.1 of [MIME].


Section 5.1 of RFC 2045:

    value := token / quoted-string

"token" doesn't allow UTF-8 (I think), but quoted-strings does, if 
updated by RFC 6532.

So, can I suggest that in Section 2.2, the following clarification is made:

OLD:

"value" is as defined in Section 5.1 of [MIME].

NEW:

"value" is as defined in Section 5.1 of [MIME], with "quoted-string" 
updated as specified in RFC 6532.


Best Regards,

Alexey
