If I understand correctly, OWL only allows this to be done if ZipCode and PostCode are RDF properties. However the differentiation that XML/XMLS is purely syntactical and RDF/RDFS semantic is false; XML vocabulary authors associate human-understandable meaning to their schemas (most humans will understand what is meant when an address contains a XML element called ZipCode or PostCode). But how to extend this semantic meaning to be machine processable, if the Web ontology languages won't permit it? lyndon
