When you use a HTML template, it is the template itself that controls
which fields are returned, so I am not sure to understand the benefit of
supporting the include/exclulde items on top of that.
Are you saying that there is a situation where all the fields end up
being unexpectedly dumped into the template out of your control? Maybe
there is a hidden feature I am not aware of in the template processor,
if that's the case then could you please elaborate?
