Example: Derivation of List and Component Notification 

In the first step in determining the notification status, the composition tree is expanded completely to listed substance level.

The notification status n (notification negative) has a lower priority than notification status y. This means that component C has list notification n as a result.

This means that the notification status would be derived from the values in brackets if the values for the list notification were passed up in the hierarchy.

For substance A, there is an obvious discrepancy between the list and component notification, that is, the notification status for substance A was changed by the appropriate person responsible (from n to y). This yields an overall default value for the list notification of P Lis = min(y,n,y,y,y,,y,ye,y,n,y,e,y) = n and P Reg = min(y,y,n,e,y) = n for the component notification.
