I don't think either of these drafts is quite there yet. They both discuss
various solutions at some length, but neither of them is clearly proposing
a single solution to the stated problem. draft-wing- does express a
preference, but we haven't debated that.

Have we even debated whether the solution must work properly with
untouched RFC3484-conforming hosts? I'd be very hesitant about any
solution that *requires* host updates.

Also, I don't think either draft considers the case where a dual stack
host receives a NAT64-based IPv6 address via an application layer referral,
so that DNS is not part of the picture. Are we trying to solve that
case too?

I think I'd rather see a new draft that contains only one solution. The existing
drafts could then become informational background documents.

Don't we *also* need a solution to the main problem considered by
draft-korhonen- (learn NAT64 prefix)? That isn't in the charter, but
seems important.

If the goal is Informational, this draft is a good one to adopt.
