[Zope-dev] _ (underscore) variable available in ZPublisher-only apps?

[Michael Olivier]

Is the _ variable available to ZPublisher-only apps (not full-up zope) in 
DTML?  I've tried

<dtml-var "_">  (inserts nothing)

and

<dtml-var "_.REQUEST">  (AttributeError exception on REQUEST)

and various other things, but haven't found anything to work.  Would be 
nice to have access in DTML to the request's namespace.

thanks,
Michael
