 SISO-REF-010 specifies numerical values and associated definitions for fields that are identified as enumerations in SISO Standards Products and SISO-sponsored standards published by IEEE for High Level Architecture (HLA) and Distributed Interactive Simulation (DIS). Enumerations for simulations may be applied in other architectures, such as the Test and Training Enabling Architecture (TENA).
