What prevents you, to render the body? This should handle
DTML expansion, at least for simple cases.

	def wrap(self,what):
	    REQUEST= self.REQUEST
	    return self.standard_html_header(self,REQUEST) \
	           + what(self,REQUEST) \
		   + self.standard_html_footer(self,REQUEST)

This will break, if one of the DTML objects needs arguments
not present in the current REQUEST.
