This document defines the supporting notation for encoding instructions that apply to the Generic String Encoding Rules (GSER) and, in particular, defines an encoding instruction to provide a machine-processable representation for the declaration of a GSER ChoiceOfStrings type. {[}STANDARDS-TRACK{]}},
