I am curious too... I've been using H-T for about a year and a half, 
and I've never had to query the template. My assumption is that params 
in the template are assigned by me, so I would automatically know what 
vars exist in the template.

What is/are a typical circumstance(s) where I would not already know 
what vars exist in a template and would want to use query to find out?

Thanks.
