continuing divergence in normative requirements and informative advice

There is a widening gap in between the W3C HTML5 specification and the
WHATWG HTML living standard especially in regards to accessibility
http://www.whatwg.org/specs/web-apps/current-work/multipage/introduction.html#is-this-html5?

It would appear that there is currently no unified HTML standard that can
claim to be authoritative, we have competing documents that contradict each
other, so is it the case that authors and implementors pick and choose the
requirements/advice that best suits them?

What is the W3C doing to resolve the differences?
