Registering classes to raise noncustom events in ActionScript 3

Question

I'm using ActionScript 3 in Flash Professional and I'd like my class to raise an event, not a custom event but an existing one. I've set up my class so that it extends EventDispatcher. In the documentation http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/events/EventDispa tcher.html the example declares a custom event by adding a static String variable:
class CustomDispatcher extends EventDispatcher {
        public static var ACTION:String = "action";
I assume that enables:
dispatcher.addEventListener(CustomDispatcher.ACTION, actionHandler);
or at least auto-complete when you've typed 'dispatcher.addEventListener(' into the Flash Professional IDE.
But lots of classes that raise events raise a mixture of existing noncustom events. For example if you have an instance of a flash.netFileReference and type
fileRef.addEventListener(
a long list of potential events to listen for is given including DataEvent.UPLOAD_COMPLETE_DATA, Event.SELECT, HTTPStatusEvent.HTTP_STATUS, SecurityErrorEvent.SECURITY_ERROR, etc.
If I want my class to be registered to raise those existing events, what code do I need? Preferably so that the IDE knows instances of my class may raise the event and suggests them in the addEventListener auto-complete/intellisense list.
(PS I hope it is OK to cross-post; I've asked this on StackOverflow too. I'll update either thread with a pointer to the answer.)

Laurent answered over on StackOverflow:
To make the events show up in the intellisense, you need to register them using the Event metatag:
[Event(name="eventName", type="package.eventType")]
Add this just before the classes that dispatches this event.
