[Zope] structured text with <dtml> tags?

Hello List, I'm still discovering Zope and I'm having fun with structured text. I'm wondering if there's a way to evaluate <dtml> tags in the structured text before (or after) rendering the structured text to HTML. Right now i'm using <dtml-var my_text fmt=structured-text>, which includes the DTML in the HTML without touching it. Thanks! Alex.
