So, how does this impact Web Components? It seems to fill pretty much the exact same role, but with a rather different implementation. Should I expect to see this become the new standard because there's a polyfill for it so people will start using it already, or am I gonna end up with a bunch of legacy code when something else becomes standardized? And, again like Web Components, it's duplicating functionality that's been in Internet Explorer of all places since IE5.0 with DHTML Behaviors.
Actually I have been meeting with the W3 Web Components spec author for about 2 months while we readied this. The document.register method that was recently added to the spec was in large part a byproduct of X-Tag and when browsers implement it (Firefox soon) X-Tag will use it internally in browsers that support it, as a polyfill always does. Once one browser implements the JS mentod, X-Tag will truly polyfill the method on document as well.
