Roy, thanks for taking the time to make this report.

As this is an IMAP extension, it inherits such aspects from IMAP, RFC
3501.  The beginning of RFC 3501 Section 9 says this:

        Note: [ABNF] rules MUST be followed strictly; in
        particular:

        (1) Except as noted otherwise, all alphabetic characters
        are case-insensitive.  The use of upper or lower case
        characters to define token strings is for editorial clarity
        only.  Implementations MUST accept these strings in a
        case-insensitive fashion.

The notations here such as "\Archive" match the related non-extended
notations in RFC 3501 such as "\Noselect", all done for the same
editorial style and all subject to that note in RFC 3501.

Alexey, I suggest marking this report as "rejected".

That said, while this doesn't represent an error or omission in the
spec, it certainly wouldn't have hurt to have been explicit about
this.  So I also suggest that any work the Extra working group does
related to IMAP takes an extra sentence here or there to be clear that
the items it defines are case-insensitive, and that the case shown in
the text is merely an editorial choice (perhaps just by explicitly
saying "See the ABNF notes at the beginning of RFC 3501 Section 9.").

Barry
