Either I'm having trouble understanding what you're saying, or
you're confusing a description of behavior with a description of
performance characteristics (which is what the "tag bucket" bit of
the post is talking about).

That said, it's :not() that breaks the standard rules of selectors,
in that given a default namespace ns, .foo is shorthand for
ns|*.foo, but :not(.foo) actually means ns|*:not(*|*.foo).
