What should update do?
INSERT DATA { :s :p "foo"^^xsd:string }
It affects query. BGP matching is simple entailment.
The wording must change there surely?
Either that or
SELECT * { ?s ?p "foo"^^xsd:string }
will stop matching on data now converted to "foo" without a software
change to the query engine.
Existing databases + new software will see a change.
In my experience, it is OWL tools that will be affected as they like to
use xsd:string in RDF for ontologies.
