Lots, most of the invalid HTML content doesn't have a doctype of any 
variety, and valid sites such as microsoft.com and others take HTML 4.01, in 
fact most valid major corporate sites other than W3.org seem to choose HTML 
4.01 varieties

But there are very specific conformance requirements?  but my problems 
aren't about the authors of content ignoring specifications, it's about the 
authors of User Agents ignoring them - the XML conformance rules being the 
ones in question, no-one ever attempted to help me with any arguments to 
explain that?  Is it really that indefensible?

WCAG says to use the latest version of a specification, so if XHTML was 
relevant, as accessibility is important XHTML 1.1 would be the one I'd 
chose, of the UA's that support XHTML 1.1, all of them either also support 
HTML 4.01, or have proxies in front of them to make it the case that they 
do, because of that there's simply no economic or practical reason to offer 
both XHTML 1.1 and HTML 4.01 content simultaneously, I should just offer 
HTML 4.01 to everybody since no-one is harmed.   The XHTML user agents are 
also extremely weak - lack of incremental rendering, bugs which cause valid 
documents to be marked invalid and error messages that only make sense to 
web-geeks displayed.

Why do you feel the need to ignore WCAG 1 - 11.1 ?  Or do you feel that 
XHTML 1.1 is not currently supported?  By my understanding Mozilla, Opera, 
Safari, Konqueror, IceBrowser and huge numbers of mobile browsers all 
support XHTML 1.1, indeed I cannot think of a user agent that supports XHTML 
1.0 that does not also support XHTML 1.1.
