Yes. D'oh!

Yes, but besides being crappy code, it was a contrived example, and the
data 'never' would have a format specifier. I see your point, however,
because oddities can,will, and do creep in.

Oh I agree. printf is very much a blast from the past of C.

A pro for JSON, and con for XML, although in the Spidermonkey
standalone/embeddable JS interpreter, there is an extension called 
E4X where XML objects are as flexible as JSON.
