> Currently, when sending a message out to the target service, by default the 
> WS-Addressing headers are removed while all other headers are preserved. 
> SYNAPSE-525 introduced the option to preserve WS-Addressing headers.
> The most reasonable default behavior would actually be as follows: 
> - If the SOAP header has been processed by a module engaged on the proxy 
> service, remove it when forwarding the message. 
> - If the SOAP header has not been processed by a module engaged on the proxy 
> service, preserve it and forward it to the target service. 
> Note that since only addressing is engaged by default on proxy services, the 
> current behavior is consistent with this default policy, except when security 
> or RM is enabled. In those latter cases, samples 200 and 201 clearly show 
> that the proposed behavior would be much more natural.
> We should also apply a similar default policy to responses sent back to the 
> client:
> - If the SOAP header has been processed by a module engaged by 
> Axis2FlexibleMEPClient, remove it when sending back the response. 
> - If the SOAP header has not been processed by a module engaged by 
> Axis2FlexibleMEPClient, preserve it. 
> For this case, samples 100 and 101 are interesting.
> Note that since Axis2 keeps track of processed headers using the 
> setProcessed/isProcessed methods in SOAPHeaderBlock, the proposed change 
> could be implemented in a completely generic way.
> Since there will be cases where the proposed default policy is not 
> appropriate, we should also add a generic mechanism to preserve/remove 
> specific headers.
