how to enfoce perorities in Policies in XACML.

Dear Seth and all,


<PolicySet PolicySetId="RPS:managerRole" Combining Algorithm = "deny-overrides">
 
            <PolicySet Combining Algorithm = "permit-overrides">
 
                    <PolicySetIdReference>PPPS:managerA</PolicySetIdReference>
 
                    <PolicySetIdReference>DenyPolicy</PolicySetIdReference>
 
            </PolicySet>
 
 
            <Target>
 
                Role Definition
 
            </Target>
 
                    <PolicySetIdReference>NPPS:managerA</PolicySetIdReference>
 
 
 </PolicySet>

Now in the above policy i really want to execute the policy (NPPS:managerA) shall be executed first without exceuting PPPS:managerA and DenyPolicy ??

is this possible ?

Muhammad.
