Issue Details:

issue01 - Where is the appropriate location for the status information?
Solution Approaches:
- In ODRL Version 2 Constraints shall only contain constraint elements, such as Count, or Datetime. The constraint element then shall comprise one or more operators (equals, no-grater-than), each specifying a fixed value or expression. The obvious location for the status information is within the constraint element.
- With regard to the ODRLv2 data model, the status attribute can be a member variable of the (abstract) constraint class.

Code Examples:

         <constraint>  
          <count status="2"> 
            <less-than-or-equal-to>5</less-than-or-equal-to>
          </count>
         </constraint>
