[snip of the rest of problem desc and tentative fix.]

Works for me.  I was trying to to a <dtml-tree> within a <dtml-in> and
was seeing pretty much the same namespace weirdness.  All fixed by applying
the following diff to lib/python/TreeDisplay/TreeTag.py in Zope 2.1.2 on
FreeBSD/i386 4.0-CURRENT.
