I'm happy with Addison's latest text, too.

And if they are a perfect match, that implies that the canonical forms should be the same. ...) [On the side, too: If the extension subtags are independent, then yes, ideally, they should match as you describe. But that's not what RFC 4647 says, nor is it what implementations do. So assume, for lack of better examples, that we have two independent subtags "northern" and "western" (I know these are bad examples, because such general variant subtags have explicitly been rejected). Now assume that in language xyz, whether a variant is western or not is much more important than whether it's northern or not, so the tag order would in general be xyz-western-northern, to allow the best possible fallback. In another language, say zyx, it could be that northern is more important, so everybody would use zyx-northern-western. In both cases, it would be rather clear what to use to actual users, but just using alphabetic order would be counter-productive, at least for zyx. Regards, Martin. #-#-# Martin J. Du"rst, Assoc.
