Thanks to those who tested the CSS filters I posted here a couple of weeks ago, my initial tests are now confirmed.
Opera supports neither the Language Pseudo-Class Filter nor the Namespace Attribute Selector; Safari supports the latter but not the former; and IE 5/Mac supports the former but not the latter. Mozilla about version 1.1 supports both, and IE/Windows supports neither.
So, if you’re looking for a filter for Safari or Opera, these could be good choices.
