The WmNotification.runNotification method is similar to the WmAdapterService.execute method, except that there is no input to this method. Results are delivered by calling the WmAsynchronousNotification.doNotify method, and passing it a WmRecord instance that must conform to the output signature of the polling notification node (see Specifying Notification Signatures (Document Type)). The WmRecord is constructed in exactly the same way it is constructed for adapter services (see Adapter Service Execution).
