BTW, I see this as no different than a query API providing support for rdfs:subClassOf, rdfs:subPropertyOf, etc. which like rdfs:range is schema information not explicit in the graph itself. If we are to have reliable queries based on values, we simply must not base them on literals. We have to take datatype context into account, and ideally do that with a common query API.
