I seem to recall one of the other co-authors looking into it and finding this was acceptable, but I don't recall.  Dave, can you comment?

I suggest the two places that refer to IDNS say

  Internationalized domain names MUST berepresented as A-labels as
  described in [RFC5891].

That's a current standard, and A-labels are what ToASCII was supposed to
produce.
