When you're submitting an IDN, there is probably a selection of
language tags you can pick.  These probably align with those; at
least, that's the point of the distinction in the LGR approach we did
for the root.  (The effect is supposed to be the same anyway, due to
blocking, but I don't know whether Verisign is doing that too.)
