SPARQL 1.1 compatibility?

Hi there,

I came here from using minted, a latex package but have tested the issue on pygments in pytyon too.

I tried to pygment SPARQL 1.1 query, and it looks like it's not compatible with 1.1 version. For example, if I pygment

SELECT ?s WHERE {
VALUES ?a { ex:Test }.
?s rdf:type ?a .
}

, VALUES is classifed as err instead of k.

Any plan on the updates? If not I can add the keyworsd I recognize though I can't guarantee it can be complete at the moment for PR.

Thanks!
