Yeah, we should republish that spec with updated links.

I'm not sure what that means. SVG 1.1 and 1.2 might require support for 
selectors from CSS2 in order for an SVG UA to claim conformance, but 
nothing stops an SVG UA from implementing selectors from CSS3 as well (as, 
indeed, Mozilla does).

Just reference CSS2.1.

Not off hand. This was years ago now. Check w3c-css-wg archives.
