Submission + - The forgotten MACRO language of HTML, XBL (wikipedia.org) 1
If the browsers supported XBL2, I can vision 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 experience developers be able to create fancy websites by just using DOM and not having to learn jquery.
My question is WHY is XBL dead? I think a MACRO language for HTML is a good idea.
