HR: Sounds fine with me. I can even think of this change as "just a clarification".

a) and c) are true (for me )
b) would still depend on how the source was viewed and what would be considered to be the source. However todays practice and public understanding I think b) is a true statement also. 
I can image an accessible hierarchical view of the (DOM-tree)-source called an "equivilant alternatives-view" (synchronised with the rendered content) that would satisfy checkpoint 2.1

I read the term "renderable content". Is this synonym with the DOM-tree content? Even if some content would not be visible, it still would be renderable (rendered invisible).
