It would seem very inconsistent if some attributes are set using
elem.setAttribute and others using elem.foo=bar. Would you make the
distinction based on that the attribute name starts with "on"?
One possible solution would be to be able to specify event handler
attributes in a second object, so something like:
Element.create("a", { href: "..." }, { onclick: function(e) { ... } },
"link", anotherChild);
On the other hand, it might be ok to say that all attributes whose
name start with "on" and whose value is a Function object is set using
the IDL property rather than setAttribute.
