<p>
<a href="/>
<dtml-with "PARENTS[-1]">
<dtml-var "images.logo .tag(border=0, alt='Go to Top Menu')">
</dtml-with>
</a>
</BODY></HTML>

<dtml-with "PARENTS[-1]">
</dtml-with>

gets you the root level.

Something similar to this was mentioned a few days ago on the list, 
but not exactly in the context you want. I don't have the exact 
reference.
