for some reason the above didn't work for me. But the following code (in
my standard_html_header) works when called from either methods or
documents with <!--#var standard_html_header-->  :

<dtml-tree expr="PARENTS[0]" branches_expr="objectValues(['DTML
Method'])" sort=id>
<a href="<dtml-var tree-item-url>"><dtml-var title_or_id></a>
</dtml-tree>

thanks to everyone who helped me with my "standard_html_header
difficulties" - I think this problem has taught me a little more about
the way Zope operates - still have a long way to go though :)
