The goal of the property ws-addressing.headers is to disable any outgoing addressing headers.
ODE 1.3.2 has 2 issues here:
#1 outgoing requests: the property is not applied to service invocations (SoapExternalService). It needs to be translated into AddressingConstants#DISABLE_ADDRESSING_FOR_OUT_MESSAGES and set on the invocation Options
#2 outgoing responses: the SessionOutHandler checks if headers are disable, but it's useless because the MessageContext does not contain the proper information.
