Indeed, dtml variable usually are not html quoted -- unless
they have a sticky content (come from REQUEST).

However, when you reference DTML objects, it is very
easy to get an apparently HTML quoted result:

     <dtml-var dtml_object>

will not be HTML quoted but

     <dtml-var "dtml_object">

appears to be.

In fact, the first form calls the "dtml_object" (which means render it)
while the second converts it to a string -- which returns the
source, HTML-quoted such that you can read the source in your browser.
