How can I configure explicit namespace prefixes in generated SOAP request/response?

[William Blackburn]

I have successfully created a wsdl-first web service using wsdl2java  
and CXF 2.2

I am now testing and see that the default namespace in the soap  
requests/responses generated by cxf' client/server does not use an  
explicit namespace prefix, for example a CXF client might emit:

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope";>
   <soap:Body>
      <RetrieveFormRequest xmlns="urn:ihe:iti:rfd:2007">
         <formID>_dummy</formID>
         <encodedResponse>true</encodedResponse>
         ... etc...etc...

While the server would answer:

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope";>
    <soap:Body>
        <RetrieveFormResponse xmlns="urn:ihe:iti:rfd:2007">
            <form>
                <Structured>
                ...etc...etc...

I want the elements representing my various types to be explicitly  
prefixed, as in:

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope";  
xmlns:rfd="urn:ihe:iti:rfd:2007">
    <soap:Body>
        <rfd:RetrieveFormResponse >
            <rfd:form>
                <rfd:Structured>
                ...etc...etc...

Is there any way to make this happen?

Thanks very much.
