I agree that _if the author writes the form according to the guidelines 
you just described_, he shouldn't need to give the index attribute. So 
I've made it optional and defaulting to 0. I also special-cased radio 
buttons and checkboxes so that if the attribute is omitted, it'll use the 
value to work out which one should be set.
