So much so that I've tried to teach people about them several times. There's a video from JSConfEU floating around on Youtube if you're interested . I think I managed to get the important parts right despite my nerves. I've given this sort of talk four times now, and as a result I've collected some feedback and questions from the developers I've talked to. > > 1. It looks like from the spec and the code in Glazkov's polyfill that if I add and remove the 'is' attribute, the shadow tree should apply/unapply itself to the host element.
Two things: 1. Added in markup or dynamically? The draft says it can't be added dynamically just in case... 2. The draft itself is a little unclear on "is". Early in the text, the reference was changed to say that these will be custom tags, in other words <x-map> instead of <select is="x-map">. Mozilla's x-tags is currently operating under that assumption as well. > I've not found this to be the case. See my examples for 2. below - I tried applying and unapplying the 'is' attribute to remix the unordered list using a template without success. > > >
