Since the idea of CSS2.2 was raised, there’s been some discussion as to what it should encompass, who should be responsible for the spec, and what it should be called; here’s what I think:
First, it doesn’t matter what it’s called. Whether it’s referred to as CSS2.2, CSS2.1+, CSS3 Interim, or whatever, makes no difference. It doesn’t need to have a name at all; the important thing is that we have it.

Any thoughts are my own, and any use of CSS3 properties doesn’t imply that they will or will not be supported by Opera in an upcoming release, unless otherwise explicitly stated.
