"p[a1]" will take a tiny bit longer to return "true" for such a node, but will take a lot less time to return "false" for everything else (because Gecko hashes on tagname, if nothing else). See David Hyatt's excellent article at http://www.mozilla.org/xpfe/goodcss.html for a discussion of the Gecko style system and performance. But yes, I agree that any such suggestion would have to be implementation-dependant. -Boris
