Do you want to know how the CSS WG works? Fantasai has written about:csswg, An Inside View of the CSS Working Group at W3C.
We published a new draft of Behavioral Extensions to CSS a few days ago. It changed significantly from the previous draft published in 1999. The new draft defines a binding
CSS property and :bound-element
pseudo-class. The other features are now covered by the XBL draft which is being developed by the W3C Web Application Formats Working Group.
As for the features in the draft, the binding
property allows you to link to resources in the XBL format and the :bound-element
pseudo-class matches elements that have a binding.
Comments are welcome on the www-style@w3.org
mailing list!
