There appears to be a perception that HTML4 and HTML5 are separate 
languages.  HTML4 is documented in a way that permits considerable 
variation in interpretation, specifically a number of variations that 
will affect the tuples that are produced by interpreting a document via 
RDFa.  I'm confident that Philip can produce a number of such test cases 

HTML5 introduces some new features (and removes a few others), but more 
relevant to the topic at hand captures the consensus interpretation 
between browser vendors on how to map a stream of bytes into a DOM. 
That consensus covers DOCTYPES that may differ from the one that HTML5 

Given that some of the RDFa implementations will be in Javascript and 
based on the DOM that browsers produce, it is important to be consistent 
with this.  Doing so in no way means that the algorithm is HTML5 specific.

I said more on the subject here:
