`nevow.json´ is a support module for `nevow.athena´. It's not intended to
be a complete or totally awesome JSON implementation.

JSON isn't XHTML, and the `docFactory´ and `render_*´ mechanisms are
primarily concerned with the generation of XHTML. To generate JSON,
I think you'd do better to ignore these features of Page and override
the `renderHTTP´ method instead. You won't have to deal with < being
turned into < and other such XHTML-related problems.
Hope this helps,
