I call B.S. on this one.

And that is its flaw. JSON is a nice 80/20 solution to one problem, but 
no more than that. The world is not serialized objects. XML is not 
serialized objects.

Not really. DOM [expletive deleted] but that's not at all why it [expletive deleted]. The reasons 
include backwards compatibility with early poorly designed browser DOMs, 
a cross-platform language design that limits it to a least common 
denominator, and design by committee. The need to support both 
text-markup XML and data-serialization XML really doesn't factor into it.

Check out XOM or E4X sometime to see what a really clean XML object 
model can look like without needing to subset the documents it can support.
