Right now our state change events work only for HTML radio buttons and checkboxes. We need to extend support to XUL.

Changing summary: John Gaunt is going to implement radio button state changes as part of his radio button support.

We don't need to fire a custom event from JS whenever the checked property changes. It's also legitimate to change the checked property using an attribute (rather than using the property), and your code will need to handle that case as well. A DOMAttributeChanged mutation event covers this case. You can listen for the checked attribute changing on checkboxes.

What kind of performance/bloat hit will DOMAttrModified cause, if I'm listening to it on a document node. I know it sets a flag that causes Mozilla to do extra work that it normally doesn't need to. That's why I'm using those custom events, to ensure the same performance when accessibility is turned on.

Change 'MutationEvents' to 'Events'. This isn't a mutation event that you're making here. With that change, sr=hyatt
