This looks like it will break content. E.g.:

   http://www.zapster.it/biografia/Suzy-Kendall/filmografia

     <div id="myGallery">

         <playlist version="1" xmlns="http://xspf.org/ns/0/">
         <trackList>

             <div class="imageElement">
                 <p>clicca per vedere tutti i poster</p>
                 <a href="..." title="Ingrandisci" class="open"></a>
                 <img src="..." class="full" alt="Suzy Kendall"/>
                 <img src="..." class="thumbnail" alt="Suzy Kendall"/>
             </div>
             ...

If the <playlist xmlns> causes the descendants to have the 
http://xspf.org/ns/0/ namespace instead of the HTML namespace, then they 
will no longer be rendered correctly as HTML links and images.
