title: Exclude radio buttons from a form submit, without disabling them
body: <p>I'm using some radio buttons to influence the behavior states of a jQuery widget.
  That widget can be used in a form but, since these radios don't contain any actual data, I don't want them to submit noise to the server, or cause naming conflict to whoever will use the widget in his form.</p>
  
  <p>Here are two potential solution starts, not yet satisfying though :</p>
  
  <ul>
  <li><strong>remove the <code>name</code> attribute</strong> : seems to work fine for other inputs, but turns my radios into checkboxes : it kills the link between them so selecting one doesn't unselect the others. Is there an HTML way (i.e. other than Javascript event) to bind them without a <code>name</code> attribute ?</li>
  <li><strong>disable the input</strong> : As expected, nothing is submitted, but the radios become grey and can't be clicked. Is there any way that they stay clickable yet unsubmittable, like disabled at submit time ?</li>
  </ul>
  
  <p>As far as possible, I'm rather looking for a cross-browser solution.</p>
