that the element ZipCode in my XML Schema has the same semantic meaning
as the element PostCode in your XML Schema.
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?
