Where is the right place to comment on draft-mdns-ice-candidates?

I looked at it from an ICE WG perspective, and it seems to be that since
(in RFC 5245), the candidate address can be a FQDN (section 15.1) you don't
need the special steps you have in section 3.2, because a .local address is
a FQDN (isn't it?).  I think the only novel thing would be to perhaps make
it clear that mDNS should be used for the name resolution.
