Please pardon my jumping into an old thread, but this is funny, because 
the point I was making in my post one-week old post below just 
materialised in front of me on the W3C website:

http://www.w3.org/blog/BPWG/2009/01/05/best_practices_to_develop_mobile_web_app

here is what I am getting (Firefox):

It is honorable that W3C tries to eat its own dogfood, but, as I was 
saying, XHTML breaks way too easily to be viable for the big web. The 
risk that someone somewhere injects a poisonous entity into your site is
