I think an improvement for EE would be an admin option to change the output of the HTML to fit doctypes other than XHTML.
I personally use an HTML 4.01 strict DTD.
Frequently Asked Questions About XHTML vs HTML

...Should I use XHTML or HTML?
That depends on who you ask. There are a number of technical issues with this question, which preclude a simple and short answer. In reality, the latest W3C recommendation with widespread support is HTML 4.01. Unless you actually need any of the features that XHTML offers over HTML, there is no technical reason to use XHTML.In order to actually benefit from using XHTML, you really need to understand the fundamental differences between XHTML and HTML. Such a site will only be available to a small minority of the surfing population, however.
Some web designers and developers prefer XHTML’s syntax rules over HTML’s. By following certain guidelines, you can use this syntax without technically using XHTML at all (see below). There are a number of potential pitfalls with this approach, but it is a possible way forward for those who absolutely want to type <br /> instead of <br>.
For ‘future-proofing’ your documents, using a Strict doctype is more important than whether you use XHTML or HTML.
Why do so many books and sites recommend XHTML over HTML?
When the XHTML 1.0 specification was released, many designers and developers were quite excited about it. It was XML, which was all the rage back then, yet could be used as if it were HTML, and it ‘worked in all browsers’. People saw countless possibilities with the extensibility mechanism, and when W3C stated that there would be no more versions of HTML, XHTML was seen as the future-proof alternative.Eventually some less palatable aspects of using XHTML were uncovered and the extensibility myth was debunked, but this didn’t receive quite the same amount of publicity. Many authors thus still advocate XHTML over HTML out of ignorance or because of personal preference.
