[Odrl-version2] Core Model: relationship between Action and Duty

[Francis Cave]

Hi Renato

Your example XML looks fine to me. But in this case you have a single 
Action associated with two Permissions, which seems to me to be 
contradicted by the '1' at the Permission entity end of the association 
with the Action entity in Figure 2.1. But maybe it is I who am missing 
something.

Regards,

Francis

Or please explain how the Core Model will enable such multiple constraints to be expressed without needing to use extensions.
