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 sucks but that's not at all why it sucks. 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.
