Multiple background images

Personally, the purpose of having multiple background images would be
 so that they could be placed in different positions.  I would have to
 support nesting of some sort:
background {
____ background1: url('something') top-right;
____ background2: url('something') top-right;
____ background3: url('something') top-right;
}

and in the DOM:
object.style.background.background1 = "url('something') top-right";

of course, this would probably need tweaking, but having multiple
backgrounds is just silly if you can't do anything with them.
