[Zope] Using py exp in dtml-var tag

[Michael Schulz - GIS Bearbeiter]

Dear List, 

i would like to pass the size attribute of a dtml-var tag as a python
expression or document/folder-property. 
Sth like this: <dtml-var mytext size="property_of_folder">.

I found several suggestions of expanding the dtml-rendering engine on
zope.org, but i am not sure if there is a way one could actually do it
already?

Thanks, 

Michael
