RE: ARIA roles added to the a element should be conforming in HTML5.

That's the real point. Apologies if I was too rude in my mail. All I wanted to say is that 

a) UA's have their own interpretation of what is gracefully accepted and what is not 

and

b) What will be accepted and what not regarding element nesting "fluctuates" a bit between the HTML releases

and

c) consequently, ARIA can act as "glue" here for some scenarios

So, in my opinion, a good start harmonizing this would be a sophisticated built in code check in the UA's (as already performed for well formed XHTML tags in some browsers) that can be executed on request or mandatory (to be discussed).

I know that so many code checkers exist but their existence is not tightly coupled to the development process, still their usage is considered as something "voluntarily" in the web developer scene (I also know that this viewpoint is debatable).

Anyway, still too many browsers consume gracefully what's been written only complaining by leaving out parts of the rendering or silently "allowing" things that are actually not permitted for a given HTML version. That's the real issue and should be addressed. I'm curious how W3C will actively drive this.

Yes, you are right, in HTML 4, an anchor element can only be 
placed WITHIN the H1 element. (Stefan was wrong about this, even 
if he is right that it works technically.) But according to the 
HTML 5 draft (and I believe according to HTML 3.2 as well), you 
can wrap the anchor element AROUND the H1 element, effectively 
making the heading a link (or button).
