I agree with this one,  implementations should either have a document
structure or be able to simulate it.

Nope Daniel, performance is a major issue for all browsers,
and forcing me to do a full search to satisfy a selector is not reasonable
on both that basis,  as well as invalidating any ability to do progressive
rendering.  I find that my browser is very much cpu bound in laying out and
rendering a document.
