Flex / AS3 metadata tags are handled differently when defining an interface, than when defining classes?

Question

If I use metadata tags before the interface, is it the same as before the class? I. e., Can I do

[Event(name="fooUpdate", type="com.acme.events.FooEvent")
public interface IFoozer extends IEventDispatcher
{
}

// ... now omit that metadata in the implementations ...

public class Foozer extends EventDispatcher implements IFoozer
{
    public function set bar(b:Bar):void
    {
        this.dispatchEvent(new FooEvent(FooEvent.FOO_UPDATE));
    }
}

// ... and expect it to be known in MXML ...

<acme:Foozer fooUpdate="myUpdateHandler">
  <!-- ... -->
</acme:Foozer>

Or, similarly, with [Bindable]?

Answer 1

You can define metadata [Event]in interfaces for informational purposes, but unlike functions, you cannot ensure that these implementations use these events. In my experience, you should override events in implementation classes.
