The resolution mechanism is not intended to be reversible , although by redefining resolution rules , reversibility is achievable to some extent within the limitations just discussed ( Hurst 1994 ) . A third problem arises with the approach to the semantics of QLFs that this notion of the relationship between QLF and RQLF encourages one to adopt : it is that taken by Alshawi and Crouch ( 1992 ) . This describes the semantics of QLFs via a supervaluation over the semantics of the RQLFs that they subsume .
