I note that there is a design objective that
4.8 Literal Search

It should be possible for a query to perform substring searches of RDF 
string literals.
and a requirement
3.3 Extensible Value Testing

but no requirement to be able to search on langtag of plain literals, 
nor the datatype of typed literals.
This seems like an omission, since the langtag gives vital information 
in multilingual documents. Also it may often be useful to find all 
literals with a particular datatype.

Ideally some langtag matching such as language ranges or lang tag 
fallback, as described in RFC 3066 would be best.
