Great stuff! This should work, although more complex than the DOM
traversal. 

There is something odd going on in my product though. I tried a
different approach to the problem and managed to write the finished DTML
source into a standard PropertySheet text-property. Now I rendered that
variable in a seperate and standard DTML Document like:

<dtml-with "MyCMFolder.MyProductInstance">
  <dtml-var rendered_html>
</dtml-with> 

And the dtml in "rendered_html" doesn't expand/render either. 

There must be something I'm doing drastically wrong for this to fail
:-S. 

Is there a sort of object mime-type or environment/namespace setting
that is telling the DTML Document not to expand the DTML in the
"rendered_html" property? 

( "rendered_html" contains only <dtml-var expr="5*6"> )

Thanks for all the help so far, I'm very grateful.

Greetings,
