​The Mission Operations Message Abstraction Layer (MAL) Recommended Standard defines the MAL in conformance with the service framework specified in the Mission Operations Services Concept Green Book (CCSDS 520.0-G-3). The current issue addresses the request to add a slight restriction to the MAL data model regarding polymorphism. In addition the WG took the opportunity to make a few additional changes:external data type specifications such as XML Schemas can now be used; XML is being moved to the SANA registry; type short forms are now integers rather than strings;optional fields in composites are now shown; lists are now a template rather than explicit types; unsigned integer and File data types have been added.
