FUNCTION xpfExist (value       : GENERIC)  
                   valueExsist : BOOLEAN;

This function returns FALSE if the actual argument "value" is INDETERMINATE (question), else it returns TRUE. In EDM all Inverse attribute is implemented as an aggregate. Hence, all Inverse attributes of an Entity are created when the actual object (entity instance) is created. The xpfExists() function will return TRUE when the actual argument "V" is an empty aggregate (the actual argument "V" is not INDETERMINATE) owned by a "simple Inverse attribute".
