What strange "id" and "expr" you are using....

When I read the doc, I had the impressions that "id" should be a method
name, but sure enough "/show_tree" is a very stange method name.

In earlier Zope versions, "dtml-tree" did not evaluate the "expr"
attribute (a bug). Apparently, this is still the case with
your Zope version. Otherwise, you should get a SyntaxError,
because "/visible_tree" is not a valid Python expression.

There are various HowTos at Zope.org about use of "dtml-tree".
Maybe, you should read them...
