Re: Case sensitivity on the LHS

    The IDNA model appears to be a better tradeoff: mandate that non-ASCII
    local parts are always case-insensitive, and leave mixed-case
    annotations as an *optional* technique for preserving case.

So does IDNA permit mixed-case annotation?  I was under the impression
that at one point the draft forbade the use of mixed-case annotation
with IDNA, but I can't find that prohibition in the current documents.

How exactly does mixed-case annotation work in IDNA?  You have to
somehow pass case information through the nameprep process; is the
precise algorithm actually spelled out anywhere?
