Hi John, You are really living on the edge, stretching the GPD to its limits ;-) The GPD is indeed not capable of handling complex configuration children. I think at present the best way is indeed to create a dedicated semantic element as well as an xml adapter for this kind of configurations, but I have not yet tested this myself. There is a need for the ESB project to make a dedicated ESB node, so I am very interested in the issues you run into. Please keep me posted about them.
