I have an external method that returns a string containing dtml, but I want it to evaluate the dtml and return the result. How do I do that? "evaluating dtml" means calling it.

The "__call__" of DTML methods, or, more generally, DocumentTemplates, has two positional parameters, "client" and "REQUEST", and an arbitrary number of keyword parameters. "client" is "None", a single object or a tuple of objects, "REQUEST" is "None" or a mapping, the keyword parameters are anything. The parameters determine, what bindings (i.e. name -> value mappings) are available in the DocumentTemplate's namespace. If there are conflicts, the higher priority source wins. The priority order is as follows (highest priority first): * keyword parameters * attributes of client (I am not sure about the relative priority in the case of more than one clients. I believe to remember that later clients have higher priority) * the mapping. Dieter
