Actionscript 3 :: Creating A Class For A Flash Symbol In HaXe?

I am having trouble incorporating graphical assets created in Flash with my haXe code.

In the Flash IDE, I've created a symbol with the linkage name "MySprite". I compile this into assets.swf. I know that to use symbols in this .swf from my haXe code, I need to add the following option when using the haxe compiler:

-swf-lib assets.swf

I'd now like to write a class called "MySprite" which is associated with this symbol, like so:

class MySprite extends Sprite {
public function new() {
// ...
}
}

Basically, I'd like to achieve something similar to the technique presented in this tutorial:

package {
import flash.display.*;
[Embed(source="assets.swf", symbol="MySprite")]

[Code]....

It's unclear from the haXe documentation whether this can be done, or what the syntax is for doing it.
