Question: Can XPages only be used for HTML?

The reason I'm asking is that the html/js/css code generated by your average XPage is too bloated for my taste.



I love the server side scripting/speed/pseudo-relational lookups part of the technology though.

My question: Is it possible to use XPages to generate other content than HTML, like (valid) XML and JSON, and how?

I've tried my friend Google, but he found nothing for me.
