A request for a software service utilizes a service intermediary. The service intermediary 1) checks the request to confirm that it conforms to XML well-formedness, and 2) validates the schema of the request. If the request passes both tests, then flags are appended to the request, which is sent to a service provider. The flag indicates to the service provider that the request has already been checked and validated, such that the service provider only needs to provide the requested service, without redundantly checking and validating the request.
