I tried the above in both validator.nu and validator.w3.org and both 
reported it to be invalid HTML4.1 (all flavors of it).

I disagree. I think it is particularly interesting because it 
demonstrates the disconnect between markup and DOM, which is an inherent 
difference between the two languages (i.e., HTML5 is defined in terms of 
the DOM and without understanding the DOM construction algorithm, you 
are quickly gonna get into problems... while, HTML4 seems to be DOM 
agnostic or something. Anyway, important difference - be nice to see it 
in the document.).

Ok, can you add a note to the spec stating that... so you won't forget:)
