I'm coming in late on this thread, so ignore me if this 
has already been covered... :)

It sounds like what you want is something like the following:

# docname is the variable passed in via the POST whose
# value is the name of the document to render. We use
# _.getattr(this(), docname) to retrieve the needed 
# document from the current object. Note that we use
# the "let" tag instead of REQUEST.set, which is 
# increasingly considered evil :)

<dtml-let theDoc="_.getattr(this(), docname)">
  <dtml-var theDoc>
</dtml-let>
