Re: [ietf-provreg] EPP and IDN

Hello, this is Mori of JPRS (Japan Registry Service, the domain name
registry in Japan).

I am very curious about this issue from the standpoint of a member of
registry who currently provides IDNs.

I know now is slightly worse timing for rewrite the documents and also
know the extension can handle IDNs properly, but I believe there is
still a chance for rewriting the protocol itself.  I think registries
who sell IDNs essentially do not sell Punycode strings, so it seems to
be better that IDN itself can specified in the relevant tags such as:
- <domain:name>,<domain:hostObj> in domain-07
- <host:name> in host-07
and perhaps,
- <contact:email> in contact-07 (further future?)

Thanks in advance.
