An Update on CSS 2.1

So where are we (that "we" meaning the CSS Working Group) on CSS 2.1? In short, we're making fast and excellent progress:

  • we are currently resolving the last outstanding issues ; almost all our weekly conference calls are entirely dedicated to CSS 2.1
  • the Test Suite is near completion ; the Working Group has decided, given the size of the Test Suite, that it's not realistic to review individually all tests before saying the Test Suite is completed. We will declare the Test Suite ready for implementation reports and will fix individual bugs when reported buggy by testers, browser vendors, the community, whoever. On a more personal note, I think it's the only reasonable way of dealing with a Test Suite that contains thousands and thousands of tests, some of them rather complex not only to write but also to understand when you read them. Otherwise, the review and validation process of all these tests alone will take ages...
  • given the recent changes in the spec - we resolved a lot of issues some of them pretty complicated - we may have to go back to Last Call Working Draft and then back to CR again. That's not a problem and can be relatively fast.
  • the current CR exit criteria - that we don't plan to change - are very clear (see conditions 4 and 5). The CR period could be a bit long though; we'll see.
  • the Test Suite and the CR should be available at same time and that time should be, as planned by the WG, after the summer. That should leave us enough time to reach Proposed Recommendation before the end of the year, as expected.

To the people who could complain about the duration of this process and the time needed to make this spec appear as a REC, let me say that we have a lot, really a lot of work here. The WG focuses almost solely on CSS 2.1 at this time and that's not recent. 2.1 must be released as a Web Standard because that's one of the current cornerstones of the architecture of the World Wide Web. We cannot make the next steps, CSS 3 even module by module, happen without 2.1 before.

In summary, we're on track. As expected. No reason to worry.
