Hm, good point. Browsers (even those that currently do the implied button 
thing) do allow that. Fixed.

Yeah, added. I have to say, I really don't like the changed() and 
formchanged() methods. If anyone has any better ideas for preventing 
duplication in the input="" and changed="" (or forminput="" and 
formchanged="") attributes, please let me know.

(I've renamed them to dispatchChanged() and dispatchFormChanged() for now. 
I don't know if it's better.)

This is mainly so that you can loop through the form.elements array and 
not worry about checking that each control is not a button.

Oops. The text in the appendix was wrong. Fixed.

Yes. It will only be true during submission, though.
