> CXF can act as an intermediary where it is on the one hand a service provider 
> and on the other hand the service implementation consumes other services.
> Within the outgoing interceptor chain (service consumer) it must get access 
> to the incoming message.
> An interceptor can access the incoming message with the following API:
> message.get("PREVIOUS_MESSAGE");
> Implementation proposal:
> ...
>     private Message previousMessage;
> ...
>     private PhaseInterceptorChain(PhaseInterceptorChain src) {
> ...
>         //
>         previousMessage = PhaseInterceptorChain.getCurrentMessage();
>         if (previousMessage != null) {
>             LOG.fine("Previous message available");
>         } else {
>             LOG.finest("No previous message available");
>         }
> ...
>     @SuppressWarnings("unchecked")
>     public synchronized boolean doIntercept(Message message) {
>         updateIterator();
>         pausedMessage = message;
>       // add the incoming message to the current message
>       if (previousMessage != null) {
>           message.put("PREVIOUS_MESSAGE", previousMessage);
>       }
>       
>         Message oldMessage = CURRENT_MESSAGE.get();
> ...
> have to do some testing on this
