[Zope] Structured Text (Again)

[Learned]

I'm sorry to be so dense about this, but I seem
to be missing something fundamental.  I see where
you are going with that, but I'm still hitting
a brick wall on one piece.

Assume the following code is building my
dynamic menu of documents:

<ul>
  <dtml-in expr="objectValues('DTML Document')">
  <li><a href="&dtml-absolute_url;"><dtml-var title_or_id></a></li><br>
  </dtml-in>
</ul>

how does the href get coded to utilize showdoc? I thought
I had it, but any version I've tried abends on me.

Thanks for your patience.
