I think it is important to point at that the service-route is not the ideal service compositioning mechanism, it is just one possible tool. This is also related to the currently very active loose-routing thread. I belive adding complexity to the existing route header is worse than adding complexity to the protocol with a new relative simple header. > >> >>If a message contains both route-headers and service-route-headers, it is a >>result of an error and the damage is minimized by just go for the route. >> >I think this should be repeated in section 4.2.
