No, they don't. Setting the event handler IDL attribute doesn't affect
the content attribute in Presto, Gecko, or WebKit. Testcase:
data:text/html,<body><script>document.documentElement.onclick =
function() { alert("I'm here"); };
alert(document.documentElement.hasAttribute("onclick"));</script></body>
Now _setting_ the content attribute on an HTML element will affect the
value stored in the event handler IDL attribute. But that's not a
reflection; it's just one-way change propagation. The IDL attributes
can exist just fine without the content attributes; you just can't set
them using setAttribute in that situation is all.

See above?

Sure. I understand the reasons the spec is what it is now. I'm just
not sure it's where we want to be.
