I fear "dtml-tree" requires a list of objects not mappings.

In principle, yes. But it would be quite some work.

I would go a different route:

  *  extend "ZPublisher.HTTPRequest.record" by a useful "__init__" method:

	    def __init__(self,**kw):
	      d= self.__dict__
	      for k,v in kw.items(): d[k]= v

  *  make it accessible from Python Scripts and ZPT by providing some useful
     security declarations

  *  make it available to DTML by adding it to "TemplateDict"
     in "DocumentTemplate.DT_Util".

This would make simple "record" instance construction available
for TTW code, something lacking from Zope!
