Talk:ControlAct level batching

I'm having trouble understanding the use case. If I query for a history of prescriptions then it appears that the batch can only return those with the *same* control act metadata, vis: "The container is designed to permit batching of multiple payloads that have the same administrative data (e.g. ControlAct author, etc), whilst allowing error information to be returned for individual items." It seems likely to me that the query response could be incomplete, because some of the requested data would have had different author/overseer/dataenter/information recipient, and therefore could not returned under the same wrapper. Is this correct? And how do I know if a query response is incomplete?Robert grant
