Most likely, you need to move your interceptor down in the chain a little, at
least beyond the SoapOutInterceptor. The SoapOutInterceptor would be
responsible for setting up and creating the SOAP:Envelope and Body and such,
but with your interceptor running before it, the call to sm.getSOAPHeader()
already creates those and they kind of blow up trying to add additional nodes.
