I think there may be some "scoping" problems in the implementation.
Unfortunately I haven't dug deep enough into the python code to track the
evaluation stack passing.

I'm using this code to try to track the sequence of things.
Each of the documents that I created simply outputs their "title_or_id".

With this, I get the expected sequence of tree +/-, entity, header, {children},
footer.

However, the references to "standard_html_footer" are messed up.
The first one gives myFooter, but the one inside the dtml-tree gives
the system footer even though it is within the same dtml-in scope.

<dtml-var standard_html_header>
<h2><dtml-var title_or_id></h2>
<p>This is the <dtml-var id> Document.</p>
<dtml-in expr="_.namespace(standard_html_header='', standard_html_footer='myFooter')">
<dtml-var standard_html_footer>
<p>
<dtml-tree Library header=dHeader footer=dFooter leaves=dLeaves>
<dtml-var dEntity>
<dtml-var standard_html_footer>
</dtml-tree>
</p>
</dtml-in>
<dtml-var standard_html_footer>
