Maybe a noob question, but: what do we mean, exactly, by "cancelling" an 
event, as in

"Authors can prevent the production of compatibility mouse events by 
cancelling the pointerdown event."

Do we mean preventDefault? return false? event.returnValue = false?

Based on your answer, I'll then file a suggestion for some clarifying 
text in the spec...
