This has been already discussed and it's very problematic. The 
conclusion was clearly "we won't do this". From the RDF spec 
perspective, the lang tag is an opaque string which syntactically 
follows RFC 5646. So no relation can be inferred (in RDF) between "en" 
and "en-GB" (that's probably the best we can do). Notice though that a 
multilingual system may apply further processing on language tags but it 
is not RDF business.

In more details:

this leads to the conclusion that strings with "en" tags are not 
distinguishable from plain sequences of characters;

and this leads to the conclusion that strings with "en" tags are not 
distinguishable from strings with "en-GB" tags.
