I would expect a policy can be more than one assertion.  Any counter-arguments?

Ken,

 

Can’t a policy be one or more assertions? The 2009 OASIS Reference Architecture draft mentioned “polices are subjective assertions made by…” and

“attribute assertions are evaluated according to the constraints in the authorization policy”

Don,

 

There is currently no definition for policy assertion.  The operative definition for policy is:

 

A policy is an assertion made by a stakeholder which the stakeholder commits to uphold and, if possible and necessary, enforce through stated constraints.

 

The term assertion is being used in its typical dictionary definition and so won’t itself be defined.

Ken,

 

Is there a published definition by OASIS for policy assertion?
