AXIS 1.0 vs. 1.1 SOAP Header support

[Rh...@sybase.com]

I am targetting the www.whitemesa.net site for interop testing of SOAP
Headers.  With ApacheAXIS 1.0, I can sucessfully send and receive soap
headers; however, with ApacheAXIS 1.1, the soap response contains no
header.  I have tracked this to AXIS requiring a namespace URI in
org.apache.axis.message.SOAPHeaderElement.java as follows:

    public SOAPHeaderElement(Element elem)
    {
        super(elem);

        // FIXME : This needs to come from someplace reasonable, perhaps
        // TLS (SOAPConstants.getCurrentVersion() ?)
        SOAPConstants soapConstants = SOAPConstants.SOAP11_CONSTANTS;

        if (getNamespaceURI()
.equals(SOAPConstants.SOAP12_CONSTANTS.getEnvelopeURI()))
            soapConstants = SOAPConstants.SOAP12_CONSTANTS;
...
    }

i.e, if the List (using WSIF's ApacheAXIS provider) that is built up to set
the context of the WSIFMessage contains an org.w3c.dom.Element that has no
namespaceURI associated with, a NullPointerException occurs during the
namespaceURI() call.  If, however, I build the Element with
Document.createElementNS(...) thus adding a namespace, I receive no
response header with Axis 1.1.  The basic reason for this is that the
message "hello world" is somehow disappearing with AXIS 1.1, although I
have verified that "hello world" is indeed contained in the Element.
Perhaps the namespace I chose, the targetNamespace of the WSDL doc, when
building the Element is incorrrect?  I have a gut feel that this is an
ApacheAXIS 1.1 problem and not WSIF, but wanted to provide a complete
picture.

Any ideas?

The code <incomplete here> used to build the Element is as follows:

----
      ArrayList domList = new ArrayList();

      // Get context information for this binding.
      WSIFMessage context = null;
      context = wsifOp.getContext();

      // Builder DOM from XML and add it to our domList.
      DocumentBuilder parser =
DocumentBuilderFactory.newInstance().newDocumentBuilder();
      Document document = parser.parse(new
InputSource(part.getContentReader()));
      // Axis1.1
      //Element elem =
document.createElementNS(getDefinition().getTargetNamespace(), headerName
);
      // Axis1.0
      Element elem = document.getDocumentElement();
      domList.add(elem);

      // Update the WSIF Operation's context.
      context.setObjectPart( WSIFConstants.CONTEXT_REQUEST_SOAP_HEADERS,
domList );
      wsifOp.setContext(context);
