I don't think that web service concatenation is an intended application for
WS-Routing. WS-Routing defines a mechanism to route a message through a
series of SOAP intermediaries on its way to the ultimate receiver. The
original question involved concatenating two ultimate receivers.

The new W3C WS Choreography Working Group proposes to define a language
which would allow you to create a composite web service that would
coordinate this type of process. The announcement for the group only came
out yesterday, so they haven't delivered very much yet. You might look at
WSCI (http://www.w3.org/TR/wsci/).

You also might look at Collaxa (http://www.collaxa.com/home.index.jsp). I
think they can do something like this. But you still have to create a new
service that coordinates the concatenation.
