Notation of the general syntax:

–All separate entities in a message are represented between curly brackets, e.g. {CRC}

–Literal strings are between quotes, e.g. 'P'

–Logical entities are neither between brackets nor quotes, e.g. Mic.-No.(microphone number)

–A logical entity will also contain a number between brackets. This number states how many characters the entity exists of, e.g.(4)

–If the subtext 1+ is attached to the entity between curly brackets, this means that one or more occurrences of this entity may occur
