SOAP Envelope Namespace

Hello,

The CXF 2.7 client is producing a SOAP envelope with the following
namespace:

But the server implementing this WS expects:

And return the SOAP fault:
/Couldn't create SOAP message. Expecting Envelope in namespace
http://www.w3.org/2003/05/soap-envelope, but got
http://schemas.xmlsoap.org/soap/envelope//

Is it possible to tune CXF and make it use the wanted namespace?

Thanks,
Gérald
