If > so, why not code them directly into XACML policies? I thought about this too (I just didn't want to make my mail even longer), in general I agree this would be the cleanest solution. However in my specific case, the organisations share a common policy database (and PDP), so I would rather have the organisations handle their contracts as attributes, instead of creating policies in a shared policy database every time a new contract is made.
