[RQ7.8] This structure shall be used to transmit NonSafetyData values (e.g. diagnostic information) together with SafetyData consistently. NonSafetyData is not CRC-protected and can stem from an unsafe source.

[RQ7.9] When presented to the safety application (e.g. at an output of the SafetyConsumer), non-safety values shall clearly be indicated as “non-safety” by an appropriate vendor-specific mechanism (e.g. by using a different colour).

To avoid possible problems with empty structures, the dummy structure NonSafetyDataPlaceholder shall be used when no NonSafetyData is used (see requirement RQ6.8).
