[ZDP] BackTalk to Document The Zope Book (2.5 Edition)/Variables and Advanced DTML

A comment to the paragraph below was recently added via http://www.zope.org/Documentation/Books/ZopeBook/current/AdvDTML.stx#2-18
The request namespace is always on the bottom of the DTML namespace
stack, and is therefore the last namespace to be looked in for names.
This means that we must be explicit in our example about which
namespace we want. We can do this with the DTML 'with' tag::
<dtml-with REQUEST only>
<form action="<dtml-var URL>" method="GET">
<input type="submit" value="What is zooName?">

Unfortunately, it's also going to look in just the REQUEST namespace for the URL variable. For a URL this is
probably ok, as it should be part of the REQUEST, but don't get tripped up.

How do you get items into the REQUEST namespace? And is there a complete reference for dealing exclusively
with this item alone?

REQUEST.set will work. See the Zope help system API reference for the REUQUEST object.

Well, the basic effect of <dtml-with ...> is to push another object onto the namespace, with <dtml-with
object only> restricting the lookup to just this object.
While sufficient to make the example work, this doesn't explain dtml-with (although it makes the impression).
