ServiceSpecificationRole is an abstract base class that defines a ServiceSpecification in terms of a set of roles. The roles are then used to characterize the shared functionality of the Service, regardless of whether it is a resource or a customer facing service.<br/><br/>ServiceSpecificationRoles represent the shared functionality of a ServiceRole. Representing a Service in terms of ServiceSpecificationRoles enables the functionality of the Service to be defined independently of BusinessActor, PhysicalResource, LogicalResource, or other Services.<br/>
