MessageElement.getNamespaceURI() results in a NullPointer if element has an href that 
does not successfuly resolve

           Summary: MessageElement.getNamespaceURI() results in a
                    NullPointer if element has an href that does not
                    successfuly resolve

When a message element has an href that fails to resolve, you can not lookup 
namespace URI by prefix, and you can not lookup prefixes by namespace.

Patch provided is for 1.0 build, but current nightly build still has the same 
problem.

Sample JUnit test:
    public void testMessageElementNullOngetNamespaceURI() throws Exception{
        String data="<anElement xmlns:ns1=\"aNamespace\" 
href=\"unknownProtocol://data\"/>";
        data="<SOAP-ENV:Envelope xmlns:SOAP-
ENV=\"http://schemas.xmlsoap.org/soap/envelope/\";><SOAP-ENV:Body>"+
             data+"</SOAP-ENV:Body></SOAP-ENV:Envelope>";
        MessageContext ctx=new MessageContext(new AxisClient());
        DeserializationContext dser = new DeserializationContextImpl(
                                           new org.xml.sax.InputSource(new 
StringReader(data)),
                                           ctx,
                                           Message.REQUEST);
        dser.parse();
                MessageElement elem=dser.getEnvelope().getBodyByName
("","anElement");
        assertEquals("aNamespace",elem.getNamespaceURI("ns1"));
        assertEquals("ns1",elem.getPrefix("aNamespace"));
    }
