EndUserObligatedbeing True indicates that the machine‘s activity is the responsibility of the end user/operator.

MachineBuilderObligatedbeing True indicates that the machine’s activity is the responsibility of the machine builder.

Typically, only one of EndUserObligatedor MachineBuilderObligatedis True, indicating the respective entity as responsible. Both being False indicates the obligation being unclear (e.g. unknown, third entity responsible). Both variables being True should not be used. It is foreseen that further obligation entities may be added in later versions; this way of representation allows for extension.
