                <p>
                    In this sample, the event (order request) is transformed into a new order with
                    a different namesapce using the XSLT mediator. Invoke the client as follows.

                <p>
                    Event will be mediated through the 'PublicEventSource' sequence and get transformed
                    before it gets published to the event sink (Axis2 server).
