Henrik;
In your scenario below, is it possible for the front end to add
something to the body before forwarding it to the back end? I ask
because I unwittingly did an example for the Primer with just your
architecture (shown below) but needed to add a body block in the "front
end". (I can elaborate separately if you wish)

Well, it is an attempt of indicating *what* it means to act in the role
of the default/anonymous actor rather than *how* to do it. The reason
for this is that *who* is the ultimate recipient depends on from what
side one is looking.
In the scenario that I brought up some time ago about a front-end server
and a back-end server like this:
sender --> front-end --> back-end
the *sender* believes that front-end it the ultimate destination. While
this is true, the front-end has off-loaded the actual processing to the
back-end. All three parties are SOAP nodes, it is just that the way the
front-end has decided to process the message is to forward the message
to the back-end server.
In short, this model implicitly supports both intermediaries as well as
gateways. I am concerned that if we don't allow this then we will have
to define a SOAP node as an abstract entity that can contain multiple
nested SOAP nodes which in my mind is much more complicated.
