Maybe that's just a terminology issue but it causes confusion regarding the
way how the messages are routed. 
In DIME we had this discussion regarding the routing of messages and Glen
clarified these aspects. 

I would also think it is extremely important to put a sort of architecture
picture in the Diameter ERP document that illustrates how the messages are
routed and how the entities relate to each other so that we aren't always
talking past each other.
