This section discusses changes to the Query Web service.
For details on any of these changes, see the Web Services and XQuery Developer's Guide.
In previous releases, the MDEX Web service was know as the Query Web service.
In earlier versions, the MDEX Web service had incomplete error handling. Web services that failed because of exceptions thrown by external functions returned a SOAP fault that included only the description field associated with the exception, and all SOAP Faults were classified as server errors.
Now, when the MDEX Web service encounters a runtime error, it can catch, package, and return the error.
These changes may break existing Web service clients that depend on the SOAP Fault Schema.
