+   Ideally we would obtain the WSDL from the remote server using <wsdl:import location="..."/>, but this
+   causes major problems if the server is down because the unresolved import causes the contribution load
+   to fail.  A simple workaround is to use a local WSDL definition that matches the service we are attempting
+   to invoke.  This ensures that the contribution can always be loaded.  If the service invocation fails at
+   runtime because the server is down, there is code in the demo to catch the exception and use local
+   historical data instead.
