Serving XHTML as application/xhtml+xml
When you're coding XHTML, you should deliver it as application/xhtml+xml. The problem is however, that once you do that, IE 6 & 7 break horribly... For your pages to render properly in those browsers, you'd need to set the mime type to text/html. Some very bright people have thought this problem in the past and came up with a real good solution in PHP, which you can find here: serving up XHTML with the correct MIME type.
WordPress though is always served as XHTML, so if possible, it should send the proper MIME type. I wrote a small plugin that does that: XHTML MIME type plugin. It doesn't work on this blog yet because of some modifications I've done, but I'll try to get it working.

Lately I've been searching for an solution to the application/xhtml+xml problem in IE too. I found a lot of sites like the one you link to, with complex checks.
First I had some troubles on understanding all these checks and I builded an easier one myself, which is included below, until I just saw your link. Some searching after that I found out that it was meant to sniff for browsers q-rating.
This didn't change my opinion that these checks are unnecessary complex. My checks work good in modern versions of Firefox, Opera and Netscape and it servers text/html nicely to IE. The only really problem I read about was for inline in Opera 7.x. As I'm not intending to use this, I don't see any problem with my little script :)
If there's something I've missed, I'd gladly hear back from you guys ;)
