[Zope] is dtml-in doing a dtml-with? How do I turn off that behaviour?

Yes and no. dtml-in actually makes each object in the iteration sequence
part of the namespace. For instance (untested):
<dtml-in objectValues>
...
</dtml-in>

<dtml-in objectIds>
<dtml-with sequence-item>
....
</dtml-with>
</dtml-in>

are equivalent.

<dtml-in> does not 'do' anything to the objects in the sequence, it is
objectValues that does the job, by returning a sequence of objects.
objectIds however returns just their ids.

Extra parameters aside, the dtml-in tag behaves like a python for loop.
Probably you can find descriptions of the extra parameters in the Zope
Quick Reference as well as descriptions of objectIds,objectValues etc
