It is covered by the UTS46 mapping table actually.

Okay. It is sometimes a bit unclear to me if people are considering
the whole of UTS46 to be transitional or just its Transitional
Processing.

Right, that algorithm does not really define what input it takes, that
it takes UseSTD3ASCIIRules as flag, that it takes some kind of marker
to indicate the processing desired, and that it returns something.

I just did. And I think I might have before as I remember seeing that
form. Might I suggest getting a public list or Bugzilla instance so
both sides can track what is going on?
