Something like that, maybe a little more concrete, e.g. "When the user 
presses a button on the pointer device, a 'mousedown' event MUST be 
dispatched at the element that is rendered at the highest z-order position 
below the current pointer position, with the event set having the 
following values: [...]" followed by the default action being to fire 
'mouseup' or 'click' or whatever, with the same detail for that, and also 
with rules for how to handle mouseover, mouseenter, mouseleave, etc. Same 
for keyboards, mousewheels, etc. Basically any user interaction event.
