  <p>Let's say that you have a list that contains 300 elements, but you only want to show the first 10, or for some
  reason you want to show elements 101-120 (Yes, I know what you really want is to be able to page through them - be
  patient that example is coming up).</p>

  <p>You can use the <code>length</code> and <code>offset</code> attributes to limit the display to only portions of
  your List.</p>
