This association establishes a ServiceAccessPoint as a requestor of protocol services from a ProtocolEndpoint. Typically, this association runs between SAPs and endpoints on a single system. Because a ProtocolEndpoint is a kind of ServiceAccessPoint, this binding can be used to establish a layering of two protocols, with the upper layer represented by the Dependent and the lower layer represented by the Antecedent.
