      Description

      According to spec - If returnType is not one of the types defined in
      XPathConstants, then an IllegalArgumentException is thrown.

      XPath.evaluate(java.lang.String expression, InputSource source, QName returnType)
      and
      XPath.evaluate(java.lang.String expression, java.net.URL documentURL, QName returnType)
      does not throw IAE when returnType is not one of the types defined in XPathConstants .
