WG Review: Internationalized Domain Name (idn)

[Lisa Dusseault]

Hi Ted,

I'm responding to part of this and excerpting.

Unicode experts have been participating in the work already, so this  
is even closer cooperation than having a liaison.  If there turns out  
to be a need for a liaison, can IAB/liaisons/ADs/chairs do lazy  
evaluation then on whether the IETF liaison can/will handle it or if  
the WG needs to create one?

That's quite possible.  Is that level of detail required in the  
charter?  I don't think there's consensus pre-WG about how to make  
requirements for IDNs in identifiers, but this is something a WG  
could reasonably tackle within the context of this charter -- in fact  
it's something that would be hard to decide how to approach before  
having a WG.

I think you're suggesting removing the parenthetical from the charter  
sentence.  Question for others: does that lose something important?   
If so how can that be made compatible with the design direction  that  
the charter suggests the WG needs to verify?

thx,
Lisa
