Where else would you expect CSS selector tests to go?

But you would have a hard time proving it, if you implement neither HTML
nor XML.

I don't recall mentioning that it had? Implementing 'all of CSS' is
something as yet unattained, naturally, for any product.

Right. And Amaya shows that adding xml:id support to an existing CSS
implementation is trivial, so (assuming the CSS implementors are, in
fact, interested in using CSS with XML) it would seem that they could
add it very easily.
