TimeSynchronization – this is an instance of the MDISTimeSyncObjectType object, that allows a Client to provide time information to a Server if required. See 6.1.16 for additional details.

Signatures is a folder that contains all of the currently available signatures (profiles). The individual signature(s) are stored as FileObjects and the format of the file(s) is vendor specific.

MDISVersion provides information about the version of the MDIS specification that is implemented by the Server. This is provided to assist the Client in determining what should be available and can also be used for automated testing of the Server.
