 /**
 21  
  * Implements a component that manages an HTML &lt;input type=submit&gt; form element. [ <a
 22  
  * href="../../../../../components/form/submit.html">Component Reference </a>]
 23  
  * <p>
 24  
  * This component is generally only used when the form has multiple submit buttons, and it is
 25  
  * important for the application to know which one was pressed. You may also want to use
 26  
  * {@link ImageSubmit}which accomplishes much the same thing, but uses a graphic image instead.
