Earlier in this thread we were originally talking about "event handler content attributers" and the possibility of doing something in ES Annex B to help define them.  But if they are WebIDL exotic functions then maybe that doesn't make so much sense.

My sense is that what we are missing is an "architecture" that actually defines how HTML and ES integrates.
