Yes, I'd already read that.

I don't fully understand how it's a halting problem, though I'm not one 
who's implementing it, so maybe it is.  Why can't it just detect if an 
event handler is attached to it during the capture, or bubble phase?  It 
wouldn't matter if, technically, the attached function essentially does 
nothing, only that there is a handler attached to the element.  Or have 
I completely misunderstood everything here?
