[Zope] DTML examples in structured text

Hi, If I want to put some example DTML code in Structured Text, how do I get the structured-text rendered without having the DTML interpreted? Here's what I'm thinking of... Blah blah blah blah blah, for example:: <dtml-var standard_html_header> foo... <dtml-var standard_html_footer> Right now, the header and footer are getting rendered when I do a <dtml-var info_stx fmt="structured-text"> Thanks, Kevin
