[idn] additional comments from draft-ietf-idnra-00.txt

[James Seng]

I am now in Beijing and they raise a issue over IDNRA.

In particular,

a) They dont think whole picture of IDNRA is complete.
   They feel there is some hidden field in RACE proposal
   or else why not use UTF-8 on the DNS query & response.

b) If there is no functional difference between UTF-8 &
   RACE, then in this case, there is no reason to waste
   CPU time to convert UTF-8 to RACE.

   Or alternatively, why not use at the RACE API level.
