Full agreement.

My point was only that the IDNA does not intend to correct the fact 
that "" cannot be linguistically reciprocated easily by AFNIC 
to a chinese competitor of Dior. It can therefore be considered as a 
WTO TBT (Technical Barrier to Trade) and I understand that some 
actions are considered or under consideration from what I read a few days ago.

I did not digest IDNAbis yet. It seems a top work. This is why I 
suggested that documenting in detail the technical requirements and 
their reasons, as well as the conditions to overcome them, could only 
help its system acceptance and R&D cooperation, and decrease 
political objections. The worst would be that another approach be 
demanded now. While, if I am correct, IDNAbis does not preclude such 
a further approach to be studied and benefit from the first 
experience. Nothing more.

Best. jfc
