Lyo OSLC read raw xml rdf response from DOORS

 I am using the following sample code to retrieve requirements data from DOORS by URL, which is derived from the eclipse lyo code examples, I can see the requirement data parsed into the "requirement" object, but I need to get the raw response (XML RDF) instead

      ClientResponse response = client.getResource(url, OslcMediaType.APPLICATION_RDF_XML);
      System.setProperty(AbstractOslcRdfXmlProvider.OSLC4J_STRICT_DATATYPES, "false");
      Requirement requirement = new Requirement();
      requirement = response.getEntity(Requirement.class);
