Well, your forced XHTML page seams to work fine in FireFox1.0.7, but
not in IE as you expected.
As a thaught, if you want to serve HTML in stead of XHTML, I would just
serve HTML4.01Strict too both browsers as it is a lot less work and may
save a lot of problems when rendering between, say IE7 and previous
versions of Ie. I also think that useing XHTML at the moment is a bit
pointless, as not even some PDA's support it.
