As required in the Baseline Requirements, yes.

None of this is impacted by Gerv's proposal.

Yes, it would be.

And this would not be affected.

Can you please explain why you believe this to be, considering that domains
are expressed as A-labels using IDNA syntax (aka Punycode)?
> Would all of these cases, using local people to do portions of the domain

That's great. Please consider that I think all companies, hopefully
including CAs, want systems to be secure. This only affects the domain
validation portion, which, through the power of a global Internet, is
something that does not require being in Freedonia or speaking Freedonian

Actually, these points were discussed during the F2F meeting, and I am once
again saddened by the non-participation.
