[Zope] Changing default content for DTML Documents?

[Alex Coventry]

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.
