[ZPT] Using TALES in a Product ..

[Ulrich Eck]

I want to make use of TALES in some kind of property-tab that 
define expressions for data-retrieval.

What do I need to include and care to write something like

here/mycontainer/myobject/myattribute or python:range(1,4)

I probably need to use
- Products.PageTemplates.TALES
- a self-defined Namespace ..

are there any examples how one easily can make use of TALES
in another product than PageTemplates ??

thanks for your help
