No, I don't think it would make sense to write that. The way ACEs are normally interpretted, and this is all based on the ACL model, is that they are ANDed. It's likely also to confuse a controller. I could see a pretty good argument for making an explicit statement about warning against that in the text. If the chairs and the WG don't mind, I will add that in my working copy. Eliot
