[Zope] How to create "Locked" folder tree?

[Chip Vanek]

Hi,

I need to "lock" aquisition to all me to display a tree of folders. I
have a tree navigation control called by standard_html_header that I
would like to always show a subtree of my site.  I think that I have
to limit the namespace but can't seem to get the syntax right.  How
do I lock the root of the tree tag to one specific place in the 
heirarchy?  My latest code attempt is below:


<dtml-with "PARENTS[-1].SiteRoot.Pub">
    <dtml-tree Pub branches_expr="objectValues('Folder')" sort=id>
         <a href="<dtml-var tree-item-url>/index_html">
             <dtml-var title_or_id></a>
    </dtml-tree>
</dtml-with>

Thanks for your help.
