Q1. I had missed the choice of "mis". I agree with that suggestion; we
should incorporate that into 4646bis. The problem is ameliorated
considerably once we add -3, but it doesn't disappear completely, so "mis"
remains a good choice for dealing with that situation.

Q2. The issue *does* remain, since we talk about "und" vs the absence of a
language tag, which "" represents.
