[whatwg] text/html flavor conformance checkers and <foo />

Both <foo /> and <foo/> are errors in HTML and should be flagged by a 
conformance checker.
XHTML 1.0 appendix C arguably allows a hybrid syntax which is HTML and 
XHTML at the same time. This is not relevant for HTML5 though, since 
HTML5 explicitly disallows serving XHTML as text/html, so a HTML5 
document is always either HTML or XHTML dependent on the mime type.
