In most cases, the useful data returned from an operation will be present once the operation is complete in properties such as Status, LastStatus, ReturnedDataSet, or ReturnedDataSets. However, in some cases, particularly where errors are reported, it is useful to be able to access and parse the associated command (group 0) elements. This property provides that facility, and contains one DicomDataSet for each response received. Like all similar properties, it is only valid when isReady is true.
