The Forgotten Macro Language of HTML: XBL 2.0

tvlinux writes "The web is becoming more than just a media display; there is more interaction and more special things that need to be done. Right now, jQuery is the preferred method of a very dynamic user interface. There is a W3 standard called XBL2.0. It is the macro language of HTML. To me it seems like a great idea — reusable HTML widgets, where each one is a separate object contained with in itself. You can define properties, methods, and events, each of which is self-contained. If the browsers supported XBL2, I can envision a whole ecosystem of new widgets, charts, grids and inputs that people could add to web pages just like any other HTML element. I see less experienced developers being able to create fancy websites by just using DOM and not having to learn jquery. My question: why is XBL dead? I think a macro-language for HTML is a good idea." XBL is alive and well, but only for XUL. Looks like another casualty of HTML5's rejection of XML.
