Could you please add a couple words more here? Why Ownership policy 
would need to use checking policy directly? Before considering 
different ways to implement compunication between policies I would 
like to see a real problem/example that could demonstate the need for 
some policies to comunicate. Form my stand point it should be either 
generic enough to be a part of framework or part of the wrong policy 
or the interface problem (though I could be wrong).
