[regext] EAI in EPP from a registrar point of view

[Dmitry Belyavsky <[e-mail]>]

Hello,

I think it's worth providing some thoughts about the EAI support in EPP
from a registrar's perspective.

>From a registrar's perspective, when the registry provides some feature,
the registrar has to support it in most cases. When a registry supports
EAI, the registrar should be ready to at least get an EAI address in the
<info> command on transfer.

Registrars usually got accreditation for working with more than one
registry, and have to write some registry-specific code. In the case of
EAI, the changes should require at least accepting EAI addresses from the
clients not having the ASCII ones and some mechanism providing the valid
ASCII email address in the case when such client wants to register a domain
in a registry that does not support EAI.
