If that does it, then could it be that the version of SPARQL that Peter was using was not doing D-entailment between xsd:int and xsd:integer ?  Ie: it could be that Peter's Profile used xsd:int (as that is how I had written it out in the earlier spec) and the ASK query was written with the number written out with no datatype specification, i.e. that it is a pure xsd:integer.

I should have upgraded all the RDF to use xsd:integer so that we minimise these types of issues until D-entailment works correctly everywhere. This type of thing is something Bergi should test for.
