Yes (although that does not put it in the rendering tree, for example
enable-background will not get you that content, and so on).

I agree. I am just trying to figure out how to spec it.

Well, the spec still has to describe the edge conditions, and the
freedom to which you refer might be tightened in subsequent versions
of the spec.

Sure, but that part of the answer was in response to 'what can I do
now with existing spec and tools'.
