You can call it a "subclass", or you can say it "implements" something. It's the same thing. I believe that you'll get into trouble if you try to make a class which is both a bean AND a collection. You'll end up having to make a bean which contains a collection property AND a size property. I'm not sure exactly how this is going to interact with the form population process.
