However, I believe today only IE and Opera support these events [2]. Can we add an 'if supported by the UA' to the wording to make it clear that some UAs won't dispatch these events? Of course the wording around mouseover/mouseout (which are universally supported) should not change. Bigger picture, I'm curious to hear why 'pointerenter' and 'pointerleave' weren't included in the pointer event design for IE. I've heard some web developers say that they prefer the enter/leave semantics (non-bubbling) to the over/out semantics. Thanks, Rick [1] http://dvcs.w3.org/hg/pointerevents/raw-file/tip/pointerEvents.html#compatibility-mapping-with-mouse-events [2] http://www.quirksmode.org/dom/events/mouseover.html http://lists.w3.org/Archives/Public/public-pointer-events/2012OctDec/0035.html 78969 1 jrossi 2012-11-28 01:19:30 +0000 This should be generalized to cover all compatibility mouse events. The future is that authors need only write to pointer, in which case user agents need not be required to support mouse events at all. 79375 2 jrossi 2012-12-04 03:13:36 +0000 Change made: http://dvcs.w3.org/hg/pointerevents/rev/0631b37f052a
