[Zope] Format Structured Text

[Learned]

I'm new to Zope, and trying to work thru some of the
examples while also applying them to real world
type scenarios. One of the examples in the Zope book
builds a navigation method, as follows:

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

If each of the documents that this returns is a
structured text document, how could I have the 
output formatted properly when the user selects a link?
