Unfortunately, forms can not be parsed - because this would 
require to generate all combinations of listboxes, radio-
buttons and various switches inside the form.. and wrap 
them with dirty javascript. Besides, MANY other problems 
would rise because many sensitive actions are controlled 
using forms (consider forums with "delete" or "reply" 
buttons, for example)
