This kind of modelling involves the expressiveness of OWL, as your 
example shows. So it needs not be tackled by the RDF working group, in 
my opinion. Anyway, this is already expressible in OWL 2, even in OWL 2 DL.

ex:british owl:equivalentClass [
     rdf:type rdfs:Datatype;
     owl:onDatatype rdf:PlainLiteral;
     owl:withRestrictions( [rdf:langRange "en-GB"] )
].
