title: Retrieve rendered output within same page
body: <p>I have a page that is rendered correctly. On this page I have a button and I wish to save a selection of the page as html when the user click on the button.</p>
  
  <p>I saw in MyFaces and Tomahawk that they added the tag Buffer that allows you to render into a buffer, does anyone know of anything similar for standard JSF?</p>
