Yes; either way, the test case in question really tests XML schema, rather than RDF itself. The reason I asked the question is due to recent statements about the intersection or otherwise of XSD types; I'd kinda got the impression that that XSD WG had responded with "clarification" of this. So either: xsd:integer is still a subclass of xsd:decimal (which may or may not be true with intentional semantics, regardless of the datatype L2V definition); or rather, the value space of one is a subset of the value space of the other (in which case nothing needs doing), or: xsd:integer's value space is not a subset of the value space of xsd:decimal after all, in which case I add another "What?!?" to the list, but that's a problem to raise with the xml schema people. -- jan grant, ILRT, University of Bristol. http://www.ilrt.bris.ac.uk/ Tel +44(0)117 9287088 Fax +44 (0)117 9287112 http://ioctl.org/jan/ Unfortunately, I have a very good idea how fast my keys are moving.
