Hmm, this is troubling:

        Element e1 = new SomeElementSubclass(...);
        Element e2 = e1.copy();
        anElement.appendChild(e1);
        anotherElement.appendChild(e2);

might wind up attaching the (same) element to anotherElement and leaving
anElement with nothing?

Thine alabaster cities gleam undimmed by human tears!
America! America!  God mend thine every flaw,
Confirm thy soul in self-control, thy liberty in law!
