The question is what should they be? One idea is to have ":shadow-host", which simply indicates if the current element is a shadow host or not. This is specific to shadow DOM spec, which makes it applicable in non-Web Components world Another idea would be to have ":component", which matches when an element is a custom DOM element. Yet another thought is to just add ":components-ready", which only matches on document and shares the timing of some "componentsready" DOM event. 72143 1 dglazkov 2012-08-13 20:45:15 +0000 Elliott Sprehn suggested ":unknown" for any elements that have HTMLUnknownElement backing. This seems awesome. 72918 2 dglazkov 2012-08-28 20:45:08 +0000 http://dvcs.w3.org/hg/webcomponents/rev/94e3b76fa3a2 79858 3 dglazkov 2012-12-10 20:30:47 +0000 *** Bug 20186 has been marked as a duplicate of this bug. ***
