Adding invoketarget and invokeaction attributes to <button> and <input type="button"> / <input type="reset"> elements would allow authors to assign behaviour to buttons in a more accessible and declarative way, while reducing bugs and simplifying the amount of JavaScript pages are required to ship for interactivity. Buttons with invoketarget will - when clicked, touched, or enacted via keypress - dispatch an InvokeEvent on the element referenced by invoketarget, with some default behaviours.
