Re: [jig] SSAC report on Single Character IDN TLDs

[Avri Doria <avri@xxxxxxx>]

Hi,

This is not an IETF product.
This is an individual draft that is being proposed.  albeit the 6th revsion of 
the individual proposal.
In fact it is an individual proposal being made by an ICANN 
volunteer/consultant and an ICANN employee.

In fact at this point in the IETF draft cycle, it would actually be useful for 
an ICANN policy group to review it and determine whether it is something we 
support or not.  And perhaps even make an IETF comment before the IAB acts on 
it.

It is certainly not an IETF end-product that should be seen as controlling over 
ICANN policy requirements.
