Sorry, you had previously written: > But for now there's still no formal model for encoding language dialects, so > BCP 47 language tags still need to use > tags for ISO 3166-1 region codes and for the script variant, and I thought you were talking about the lack of a formal model in BCP 47, not in ISO 639. In any case, this is now completely unrelated to Unicode, so I'll refrain from further postings. -- Doug Ewell | Thornton, Colorado, USA | http://www.ewellic.org RFC 5645, 4645, UTN #14 | ietf-languages @ is dot gd slash 2kf0s
