Camel CXF Proxy with WS-Security

I am writing a SOAP proxy. When a SOAP service call comes in, it goes to a
CXF consumer->Processor->CXF producer (with WS-Security)

Since the incoming service call and the outgoing service call are from
different wsdl and thus different namespace, I would need to transform the
information. How can I achieve this and then have the message body ready to
pass on to the cxf:bean:realSerive?

Thanks.
