That is consistent with my impression. My concern is that the language and terminology won't make it clear about what is being specified unless someone is _really_ familiar with IDNA and the "EAI" specs. It meshes with Patrik's concern that the wording of the spec won't be clear to someone who is not _very_ good with English. My impression is that there is little problem with the intended underlying spec, but the document text needs some tuning. john
