As Karl has pointed out privately, the registered IANA subtypes we should be mimicking are no-nyn and no-bok. Here's the definitive URL: ftp://ftp.isi.edu/in-notes/iana/assignments/languages/tags I've confirmed this with Harald Alvestrand, and he plans to fix the more general IETF draft I cited to keep other folks from being confused like I was: http://www.ietf.org/internet-drafts/draft-alvestrand-lang-tags-v2-00.txt Also, he encouraged anyone introducing translations for languages which don't already have a subtag to go ahead and register them with IANA. I've never done this, but he says it's not hard. :-) Paul
