xsd:int is not promoted to xsd:integer in filters #381

The following query won't return anything from the http://dbpedia.org/sparql endpoint (Virtuoso 7.20).

prefix dbo: <http://dbpedia.org/ontology/>
prefix xsd: <http://www.w3.org/2001/XMLSchema#>

select * {

  ?a a dbo:Automobile; dbo:productionStartDate ?s

  bind( year(?s) as ?y )
  filter ( ?y >= '2005'^^xsd:int )

} limit 10

'2005'xsd:int is not promoted to an xsd:integer in order to match the return type of year(?s).
