I agree, I'd love to get standard annotations involved, but since we can do that later compatibly, I'm happy with the enhancement here. The only thing that bothers me about it is that the names are "magic" I guess for the ResourceBundle, in that I cannot have a ResourceBundle in my FXML file with an fx:id by that name? Or things might get confusing.
