What it sounds like you want to do can be done just as easily in a DTML
Method.

<ul>
<!--#in "objectValues('Folder')"-->
  <li>A folder: <!--#var id--></li>
<!--#/in-->
</ul>

This is because a DTML Method is a method of the folder than contains
it, not an Zope object in itself.  If you put this code in a DTML
*Document* you'll get nothing.
