In fact, the RFC says something quite different. In Section 4.1 (Choice of Language Tag), item #4 says: -- The 'und' (Undetermined) primary language subtag SHOULD NOT be used to label content, even if the language is unknown. Omitting the language tag altogether is preferred to using a tag with a primary language subtag of 'und'. The 'und' subtag MAY be useful for protocols that require a language tag to be provided. The 'und' subtag MAY also be useful when matching language tags in certain situations. -- Addison -- Addison Phillips Globalization Architect -- Yahoo! Inc. Co-Editor, RFC 4646 Internationalization is an architecture. It is not a feature.
