> When the 1.0 draft was published as a Candidate Recommendation, it 
turned out that it was slightly different from another specification, 
called WCSS 1, published by the OMA (Open Mobile Alliance). Since then, 
W3C and OMA decided to work together on a common profile. This is the 
first draft.

** 2017年

[22] [[CSS 2.2]]、[[CSS 2.3]] が準備されていましたが、これらの名前は廃止され、
[[CSS 2.1]] の改訂版として発行されることになりました。場所によっては [[CSS2]]
と表記されています。

[23] つまり実質的に[[バージョン番号の廃止][バージョニングの失敗]]なのですが、
既に分割されたモジュール仕様書はそのままの形で開発が継続されていて、
古い [[CSS2]] だけバージョン番号を変えずに改訂を続けるという歪な形になっています。
(元の [[CSS 2.0]] や [[CSS 2.1]] とは違って、新しいモジュール仕様書が発行された部分は削除されています。)

[24] [TIME[2月][2017-02]]には、 [CITE[CSS Snapshot 2017]] が出版されています。

> Antenna House (an implementor of XSL and represented on the XSL Working Group) gave a presentation about their desire for greater compatibility between CSS, and especially the CSS 3 drafts, and XSL-FO.
> This proposal has been withdrawn.
> There was a discussion on CSS compatibility at another occasion during the Workshop. Everyone wanted it, but in fact there were zero votes for compatibility with 3.0, one or two votes for compatibility with CSS 2.1, and none for CSS 2.0; no-one wanted to lost backwards compatibility with XSL-FO 1.0 or 1.1 in order to improve compatibility with the CSS 3 working drafts. A sizeable minority (more than a third) wanted the normative references to CSS removed altogether.
