Not quite right: RFC 4646 doesn't *define* zero-length tags. That is NOT 
the same as disallowing them. 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.

Internationalization is an architecture.
It is not a feature.
