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

[Chip Vanek]

Hi,

Does anyone know how to "lock" the namespace (dtml-with or dtml-let)
inside dtml to ensure that the dtml-tree tag always displays the same
tree?

Or alternatly what is the ideal syntax to create an dtml-if that
can check if the present method is below the tree tag.  I am using
the code below but, it only works if I am in the Pub folder not in
any of the children folders of Pub.  

   <dtml-if "_.getattr(PARENTS[0], 'id') == 'Pub'">
          <dtml-tree .......>
   </dtml-if>

Any help would be GREATLY appreciated.

Best,

Chip
