As I understand it, one of the fundamental tenets of the HTML5 designers 
is that all browsers should behave the same when presented with the same 
character stream. As such, I'm not sure that they could permit 
subsetting of the vocabulary, especially as there are many deliberate 
layering violations.

My impression is that this is more about rendering than DOMs, as their 
main objection to XML syntaxes is that ordinary "web designers" cannot 
be expected to conform to a formal syntax, but only to the production of 
character stream that provides the desired output, judged by that 
output, not by any theoretical transformations of the character stream 
into that output.

The main objection to XML is that "web desginers" cannot cope with the 
layering concept imposed by XML.

I suppose this could have been compromised, with the addition of SVG, in 
that they may accept that a small number of macro features may not work 
on some browsers.
