[Odrl-version2] Re: The difference between offer and ticket

[fengwenjie]

Hi Renato,

That is to say, Offer only represent the holder's ability, while Ticket means 
the holder has issued the rights. 
Then I have still another question: why the two has different contraint on 
the number of Party with Assigner role? Actually, in one negotiation, shouldn't 
the Assigner of Offer and Ticket be the same?

BR,
Jessica
