              - throw  - Throw an exception which can be caught by the global error handler defined in Application_OnError. If no such
                         error handler is defined then you'll see the Yellow Screen Of Death (YSOD) error page.
              Note the error can also be handled by the umbraco.macro.Error event, where you can log/alarm with your own code and change the behaviour per event. -->
