Web DOM Core already defines that getElementById returns the first element: <http://simon.html5.org/specs/web-dom-core#dom-document-getelementbyid>. For ID selectors, the Selectors specification implicitly defines that all elements with the given id are matched: <http://www.w3.org/TR/css3-selectors/#id-selectors>.
