Dear Dave,

I understand that you are only interested in extending the range of
domain
names beyond ASCII and are not interested in solving either TC/SC or the
CJK variants problem. We are not asking you to do that either. Unicode
and
IDNA, etc., do extend the range of domain names for you. But, in the
mean
time, it extends too much and brings too many variants of Han characters
and the associated delegation and resolution problems to Internet users
in
other culture where these characters are used in their daily life.

In other words, what you called an IDN WG solution is a partial
solution.
It works for a portion of the world but not the whole. We are asking
people
here in the WG to take the part of solution you are happy with.  But,
please
bear in mind that there is no consensus regarding the IDN "solution" on
the
CJK portion, so we urge the WG to adopt a phased implementation
strategy.
