C. ASYNCHRONOUS PROCESSING PROFILE
1. PendingRequest
This profile allows OptionalInputs?. Text says: " Any additional inputs to the request. This element may be used e.g. for authentication data"
I am not sure that in any of the optional inputs in the core there is an OptionalInput? for conveying authentication data.
Apart from that, I would not expect that in the pendingRequest would appear any optional input that repeats some of the optional inputs present in the initial request that repeats things like the server policy, the signature policy, the validation data, etc because, what if the information in this pendingRequest is different from the information in the initial request?
