  <dc:description>This file specifies in RDF Schema format the
    built-in classes and properties that together form the basis of
    the RDF/XML syntax of OWL Full, OWL DL and OWL Lite with the help  
    of RDF Schema. We do not expect people to import this file
    explicitly into their ontology. People that do import this file
    should expect their ontology to be an OWL Full ontology.
