Btw, the markup at http://samoa.sii.it/ is a good indication
of why a <box> tag will be useful. This:
<div id="container-00-gen">
<div id="container-gen">
<div id="container-top-gen">
<div id="container-puls-home"><a href="#">
<img border=0 src="/resources/01_cont_puls_kelp.png"></a></div>
<div id="container-valori-gen">
<div class="user-greeting">
Welcome, dot LRN
</div> <!-- user-greeting -->
</div> <!-- container-valori-gen -->
</div> <!-- container-top-gen -->
</div> <!-- container-gen -->
</div> <!-- container-00-gen -->
and a bunch more similiar "box" things exist throughout the design with all the extra divs there to hang background images off. Using a <box> tag would make it possible to
make the template code be something like:
<box id="container">
<div class="user-greeting">
Welcome, dot LRN
</div> <!-- user-greeting -->
</box>
and have all the supporting div's be generated both consistently and programatically.
