As I just stated in the other subthread, I believe the HTTP
Content-Type is (should be) independent of the "mode" the ZPT
machinery uses to process the template.  The <browser:page> directive
or some other suitable explicit configuration should control the
browser-specific items like content-type.  I suppose maybe the
publisher could add its two sense and handle IE and Mozilla
differently presenting a facade to IE so it doesn't trip over itself
and presenting the more-correct-by-the-spec information to Mozilla.
