Binary XML

Jimmy Zhang hits the nail on the head when he notes that parsing ASCII text is not the primary problem in XML performance, object allocation is. I was surprised by the same finding when I started working on Objective-XML around a decade ago.

Sean McGrath claims that Binary XML solves the wrong problem.

Yes and no: it doesn't help much with existing structures and parsing methods, but with the right methods, it can be extremely helpful!

Also: "...how weird is it that we have not moved on from the DOM and SAX in terms of "standard" APIs for XML processing?"
