We were planning on using this for both routing and dispatching on the invocation side (e.g. intermediaries can use this value to route this request to the "real" endpoint within a cluster that is ready to handle that type of request and within a "real" endpoint, the framework layer can use this value to decide on which callback to invoke within the service). The main reason that we saw for having this in a header is that it allows this work to be done without requiring such parties to interact with the body of the message. So, it can be opaque and useless for those who don't use it, but it can be useful for those who want to be able to do this kind of stuff without having to step into the body of the message. Conor
