Maybe I misunderstood the purpose of app-messages, but I don't see how
to use the app-message-* directives to allow more than one "response"
from the callout server. The OPES processor does app-message-start
for am-id, X, then some data, then app-message-end am-id=X, and the
callout server will respond with app-message-start am-id=X and
sometime later app-message-end am-id=X. At that point all state about
am-id=X on both machines must be destroyed. How can the callout
server send another version of the data it received from the OPES
processor and relate it to am-id=X?
