Pseudo-element proposal

Dear www-style,

We at Adobe have started working on a new specification extracting the
notion of Pseudo-Element from the Selectors REC and extending it to
allow multiple "before" and "after" pseudo-elements created by one
single element. This is useful for effects like the ones collected in

but can serve other purposes like creating boxes for CSS Regions.
It will also simplify the level 4 Selectors spec, separating
the notion and grammar of pseudo-elements from their syntax and
rendering definitions.

The proposal is available at

We have implemented a JavaScript-based prototype to allow us to
validate the syntax. The code is available at

and demos based on that prototype are available at

We expect discussion about this proposal to happen during
the forthcoming CSS WG face-to-face meeting in San Diego
and will happily respond to all feedback sent to www-style
with a leading "[css4-pseudos] " in the subject line.

Best regards,

Razvan Caliman, Adobe Systems, Inc.
