So ISO 3166 is out, too?
I'm against 2-letter codes. The number of languages is way too large for these codes to be remotely sufficient.
ISO 3166 is about country codes and about half of the codes from the 2 letter codespace seem to be used or reserved in some way ...
But should three-letter country codes be allowed?
i dont know, but i would prefer if either 2 or 3 letter codes would be used but not both ...
Each 3-letter code has a corresponding 2-letter code, and I just noticed that ISO doesn't publish the 3-letter codes for free, so I think country codes should use the 2-letter form.
In that case, how should the entire language string be formatted? Something like "lll-ccc" where both "lll" and "-ccc" are optional?
that is a good question, i also thought of lll-ccc when i was working on that part of the spec seems it was never explicitly writen in the spec though :( "-ccc" though seems invalid to me it rather should be "unk-ccc" or "mul-ccc"
New proposal: "Language" An ISO 639-2 (three-letter) language code, optionally followed by an ISO 3166-1 two-letter country code that is separated from the language code by a hyphen. All codes defined in ISO 639-2 are allowed, including "und" (Undetermined), "mul" (Multiple languages) and the bibliographic/terminology variants. see http://www.loc.gov/standards/iso639-2/php/code_list.php and http://www.iso.ch/iso/en/prods-services/iso3166ma/02iso-3166-code-lists/list... a demuxer MUST ignore unknown language and country codes instead of treating them as an error Regards, Clemens
