Right.  Except you define the data type using OWL. Which means you defined
the  lexical space to be empty.
What happens when you have a literal in RDF whose string is not in its
lexical space.

I will grant you that there are many legal RDF statements in the
vocabularies. Can you tell me what's going on with these ones?  If you
think they're fine, and perfectly consistent, feel free to just let this
thread die.


  rdf:type owl:DatatypeProperty ;

  rdfs:label "namespace"^^xsd:string ;

  rdfs:range xsd:anyURI ;



      rdf:type owl:Ontology ;

      vaem:namespace "http://qudt.org/schema/qudt"^^xsd:string ;
