DOM Clobbering

How named DOM access lets markup overwrite script variables. Two elements sharing an id or name become an HTML collection reachable as a global, self-referencing indefinitely and shadowing the element's own properties; a global assignment could rewrite a same-named anchor's href on IE; and naming a form 'self' with a location attribute defeats a top!=self framebuster.
