interfaces in *.mxml

[nirth]

Hello conf, i'm currently working on problem with implementing interfaces in mxml, i found some workaround:
some interface:

package{
interface A {
function doSomething():void;
}
}

class which implement interface, and used as base class for mxml

package{
public class B extends VBox implements A {
public function doSomething():void {};
}
}

and finally our mxml

<?xml version="1.0" encoding="utf-8"?>
<B xmlns:mx="http://www.adobe.com/2006/mxml">
<!-- some stuff goes here -->
</B>

but i dont really like this way, is there any way to implement interface directly?
