At the first glance I like it.
--------

What I'm missing most now is to add Navigable principle back to it or 
alternatively some of the other principles need to include it more strongly 
than they do now (I prefer to add it). Navigation seems to be nowhere now 
when you read the principles and guidelines. Still it is one of the key 
things in helping users to create a mental model of the page and be able to 
jump to important content, or skip less important things when needed to. It 
helps people who use sequential means to travel through the page and it is 
always in the visual interface if it is done well. If the language offers 
some mark-up for grouping and IDs for easily identifying the parts it helps 
the navigation even more, but those can go to the language level and/or XAG.

Guideline for being able to use different audio, visual, braille etc. 
presentations for these structures then goes under it also.

(I missed why the navigation was taken out, sorry about that.)
