     CCSDS 521.0-P-2.1. Mission Operations Message Abstraction Layer. 
                        Pink Book. Issue 2.1. February 2023.

DOCUMENT DESCRIPTION:  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).
