<!--
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.
