FWIW my experience is that the absolute best emacs modes (e.g. 
nxml-mode, js2-mode) implement a proper parser for the underlying 
language that they support. I would hope in time to see a HTML 5 mode 
that does the same thing and would hope that we would not actively 
discourage that by directing authors of such tools away from the HTML 5 
spec to the Markup Language spec.

There is the question of the difficulty of separating two parts of the 
spec. Making this document normative and keeping with the sane policy of 
only defining everything exactly once implies an undertaking of effort 
to remove all the corresponding text from the HTML 5 draft, create a 
complex web of normative references and ongoing effort to ensure the 
documents remain in lockstep with each other; a process that seems to be 
highly unreliable. This is a significant amount of work (indeed it has 
been noted that the drafts are already out of sync), yet the appeal of 
the Markup language spec seems to be to people in the set ((producing an 
HTML document | producing a tool to produce HTML documents) & don't 
require APIs or scripting & don't need to consume HTML & understand 
complex formal languages). As far as I can tell this leaves a small 
subset of authors and a probably small subset of authoring tools. 
Everyone else will need to look at the HTML 5 spec proper. Given the 
likely complexity of making the split and the apparently small group of 
beneficiaries, I don't see the value proposition for making this 
document normative adding up. I don't think the existence of other cases 
in which the value proposition did add up should be used a priori as 
evidence that the same will be true in this case.
