Ok, let me do the first try (BTW, I am referencing draft-alvestrand-lang-tags-v2-00.txt, not RFC 1766): >4. LANGUAGE Command > > Arguments: Zero or one language tag as defined by [RFC-1766]. Add the following text: "Language tags MUL (Multiple languages) and Und (Undetermined) MUST NOT be used." Same text should be added to ABNF section. After the text > If a sublanguage was asked for and not available but the > primary language is available, the server should switch to > the primary language and include a LANGUAGE response > containing the identifier of the primary language it > switched to. add the following: It is also recommended that server recognizes languages that have multiple different tags (like "ru" and "rus"). Note 1. Client MUST NOT use MUL (Multiple languages) and Und (Undetermined) language tags and server MUST return BAD to the LANGUAGE command with such parameter. Note 2. [LANG-TAG] (draft-alvestrand-lang-tags-v2-00.txt) warns that there is no guaranteed relationship between languages whose tags start out with the same series of subtags. However it is believed that for the purpose of this document it is safe to treat all languages, whose tags starts with primary language described in ISO 639-1 and ISO 639-2 (i.e. all 2 or 3 letters primary languages) as hierarchical. For all languages with other primary tags fallback rule MUST not be used. In particular, language tags starting with 'i-' and 'x-' SHOULD NOT be treated as hierarchical. --------------- Alexey Melnikov Software Developer phone: (780) 424 4922 x 357 MessagingDirect Ltd. fax : (780) 424 4925 mailto:mel@messagingdirect.com http://www.MessagingDirect.com
