I'd just like to make sure that I interpret Zope Book's chapter 7 (Advanced DTML scripting) correctly.

"But the DTML stack is not all there is to names because DTML doesn't start with an empty stack, (...)" "the client object is the first object on the top of the DTML namespace stack." "the request namespace is always on the bottom of the DTML namespace stack (...)."

To me this sounds as if there could be a whole bunch of objects in between these two objects, but I have not seen any proof of this. So I guess I stick to this picture before execution starts?

| | | client object | top of namespace stack | | | | ...really nothing in between? | | | request | bottom of namespace stack +------------------+ There is nothing in between!

Now suppose I have a folder X, containing objects A and B. I call a script gimmeListing on X; gimmeListing uses <dtml-in objectValues>. Hence the namespace would look like this in the first iteration? Yes.
