The optional ResultTransfer Object is used to transfer the content of a result by a temporary file transfer. In order to be called by the Client, the Client first need to receive a ResultId.
The optional Results Object is used to organize available results of the system which the Server decides to expose in the AddressSpace. It may contain no result if no result is available, if the Server does not expose results in the AddressSpace at all or if no available result matches the criteria of the Server for exposure in the AddressSpace. It may contain multiple results if multiple results are available.
The components of the ResultManagementType have additional subcomponents which are defined in Table 2.
