We can break this down into two permission statements:

====Permission 1======
Asset = f
Permission = print [Constraint <= 100]
====Permission 1======

====Permission 2======
Asset = f
Permission = print [Constraint > 100]
Duty = Pay [amount = AUD5]
====Permission 2======

This way the constraint related to printing is associated with the  
Permission, not the Duty.

Is this a clearer ???
