A good question!

Everything is inherited - except if it (action) already exists in the  
Child.

....But....if you look at Figure 4.9 example - what the complete Child  
license now contains is the Display action (from Sony:999 for Nikky: 
543) AND the Print action (from Sony:999 for Billie:888)

Assuming this Child license was issued to Nikky:543, she will have a  
hard time doing the Print as she is not Billie:888 !

Comments?
