Tiny off-topic side-not on E4X: it was extremely popular in it's time... for extension author, GM scripters, XULers, anyone who had the freedom to use it without the concern of cross-browser compat. I think its failure was either one of standardisation bureaucracy, or of odd cross-client resistance to implementation, rather than it not being tech people wanted. > I would say it's remarkable how many standards on the web apparently don't have anything to do with HTML. I took the thrust of the original comment I responded to above to be giving WHATWG and general living/rolling-spec. process credit for increasing the pace of useful/practical/needed web innovations. I was pointing out that many of the cited examples of useful innovations were created either before WHATWG existed, or at least outside of WHATWG process, and that the majority (admittedly not all) of what the WHATWG has actually contributed has been superfluous cruft. That's the intent of my separating "this is part of HTML5, this isn't". Obviously many things are/can be subsumed into HTML5 as that's where they belong taxonomically, but I'm focusing on inception and what benefit living-standard process brings.
