See https://github.com/whatwg/html/issues/1026 headers and ping IDL attributes are strings but should be DOMTokenList. Spec: https://html.spec.whatwg.org/multipage/semantics.html#htmlanchorelement https://html.spec.whatwg.org/multipage/embedded-content.html#htmlareaelement https://html.spec.whatwg.org/multipage/tables.html#htmltablecellelement Simple test: <!DOCTYPE html> <a id=a ping="x y"></a> <table><tr><td id=td headers="z"></table> <script> alert(a.ping instanceof DOMTokenList); alert(td.headers instanceof DOMTokenList); </script> Test: http://w3c-test.org/html/dom/interfaces.html

Last I checked, the other browsers had not implemented it either so I delayed this work.

The spec changed .headers and .ping to DOMString/USVString in https://github.com/whatwg/html/pull/1262
