Bare Minimum ODRL

As per the actions from the last meeting [1], in reviewing the ODRL Model, the absolute bare minimum that an ODRL Policy must conform to is:
 
Section 2.1
- A Policy MUST have one uid property value to identify the Policy.
- A Policy MUST have at least one property (which has a range of a subclass of Rule).

Section 2.6
- A Rule MUST have one action property value of type Action.
