Hi, Apparently there has been discussions about hats and cats selector combinators in www-style: http://lists.w3.org/Archives/Public/www-style/2014Feb/0032.html
In that Tab (Atkins) from Google made a comment saying that Chrome will be shipping Shadow DOM in the very near future: http://lists.w3.org/Archives/Public/www-style/2014Feb/0036.html My understanding is that shadow DOM specification is still being chartered by this very WebApps working group, and unless I’m missing something, the specification was not considered stable enough for any browser vendor to ship without prefixes or behind a flag at least in the last TPAC. In fact, the current working draft has many outstanding issues including issue 6 that says “Hats, ^, and Cats, ^^, selector combinators should be defined in this section.” Also, the latest working draft doesn’t reflect recent discussions on the various mailing lists. For example, section 7.1 Ranges and Selections still mentions that selections are to be entirely within a single root: http://w3c.github.io/webcomponents/spec/shadow/#ranges-and-selection but Jonas (Sicking) from Mozilla has made a pretty strong argument for allowing selection to be extended across shadow boundaries following http://lists.w3.org/Archives/Public/public-webapps/2013OctDec/0106.html Am I completely misunderstanding the status of the specification or missing something? - R.
