[Zope] Format Structured Text

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?
