[Zope] [newbie] Property with <dtml-var> in it's value

Hi Was just a bit surprised and haven't found anything about this on zope.org ... Can anyone tell me how I can make that a <dtml-var xxxx> which is stored in a Property of a ZClass instance, will be "processed" when I reference it in a dtml method. The property is from type "text" and there is normal text in front and after the dtml-var statement. Thanks for your help Stefan Mallepell PS: I'm very sorry, that I put so many questions in to this email-list at the moment. I hope somewhen in the future I will be able to help myself other newbies ...
