Summary:                    Comparing xsd:int and xsd:integer fails in SPARQL
Description: 
Suppose this triple:
<http://test.com#123> <http://test.com#val>
"42"^^<http://www.w3.org/2001/XMLSchema#int> .

All theses SPARQL queries have to give a positive result:
SELECT ?x WHERE { ?x <http://test.com#val> ?y. FILTER( ?y > 40 ). }
SELECT ?x WHERE { ?x <http://test.com#val> ?y. FILTER( ?y >
"40"^^<http://www.w3.org/2001/XMLSchema#integer> ). }
SELECT ?x WHERE { ?x <http://test.com#val> ?y. FILTER( ?y >
"40"^^<http://www.w3.org/2001/XMLSchema#int> ). }

However, there is no results for any of these queries.

Using this triple:
<http://test.com#123> <http://test.com#val>
"42"^^<http://www.w3.org/2001/XMLSchema#integer> .

Only the two first gives the attended result.

Considering SPARQL recommendation, auto-casting from "int" to "integer" is
correct for numeric operators:
