[Zope] Changing default content for DTML Documents?

Hi. The default content for DTML Documents is incompatible with Epoz. If you point Epoz at a newly created document, and click submit, the result is the error 'Invalid attribute name, "standard_html_header", for tag <dtml-var standard_html_header="">, on line 1 of test.' To get around this, I would like newly created documents to start with no text. Is there an easy way to do this, short of changing Zope's source? Alex.
