IE does indeed return custom attributes through DOM properties (it makes 
no distinction). but this is clearly errant behavior.
as has already been discussed, there will be particular effort catering 
to IE anyway.

this is kind of silly but it makes the point: if i wrote a buggy 
browser, should WF2 try to be compatible with it?
