With the updated example, using useCapture=false, I believe that the
change events should bubble up to the FORM, through the FIELDSET, and
that the submit event should bubble up to document (even though FORM
doesn't support "change" and document doesn't support "submit"). Is my
understanding correct? Please confirm.

Also, if the answer is "yes, they should" then what about IE? Should
the MSIE event be expected to bubble?

Does having a broken event model hamper development productivity?

Can this be answered fairly by looking at existing web scripts?

Is it reasonable to try to apply parts of the DOM Event standard to
MSIE's event argument? Or should the entire event model be regarded as
completely incompatible?

I am asking because Microsoft refuses to implement addEventListener,
and this seems to be including anything related to the different event
model.

  onsubmit: http://msdn.microsoft.com/en-us/library/ms536972.aspx

Legacy events onchange and onsubmit do not bubble as registered in the
DOM 0 (I'm not suggesting this change). In FF and Saf, (e.g.
form.onchange = callback) with one caveat: In FF and Saf, "change"
event of a SELECT will bubble up.

However, ISTM that if Microsoft were to add proper support for DOM
Events, with callbacks registered via addEventListener, it would be
possible to avoid conflict with legacy events and callbacks registered
via attachEvent, and allow developers to use the standard DOM Event
model
http://www.w3.org/TR/DOM-Level-2-Events/events.html

Is there a test suite for events? Searching the web, I could not find
an EcmaScript events test suite.
