An association between a service access point and how it is   implemented in software.  The cardinality of this association  is many-to-many.  A SAP may be provided by more than one  software feature, operating in conjunction.  And, any  software feature may provide more than one service access point. a  When many software features are associated with single SAP,  it is assumed that these elements operate in conjunction to  provide the access point.  If different implementations of a  SAP exist, each of these implementations would result in  individual instantiations of the service access point object.  These individual instantiations would then have associations  to the unique implementations.
