        operation cannot be executed currently, due to a
        conflict with the state of the "Individual alarm"
        resource.
        Typically, this is due to the fact that the alarm is
        already in the state that is requested to be set (such
        as trying to acknowledge an already-acknowledged
        alarm).

        fulfilled.
        Typically, this is due to an ETag mismatch, indicating
        that the resource was modified by another entity.
