You're just wrong. ;)  "selector" in this instance is in fact everything 
between a pair of commas.  It's clearly defined in section 4 of the spec 
you cite, paragraph 1.

::outside is not implemented in any UA to my knowledge.

And ::after::after is not implemented not just due to the selector 
syntax restriction, but because the entire CSS3 generated content spec 
is more or less wishful thinking at this point.
