The function returns true if and only if instantiation1 is preferred to instantiation2 by the conflict resolution tactic - -priority
, otherwise false. The function is intended to be used primarily by including it in the conflict resolution strategy for a context.
(defcontext my-context1 :strategy (-priority))
(defcontext my-context2 :strategy (recency -priority))
