From 2008... Happy 10th Birthday to XML!
There is essentially no computer in the world, desk-top, hand-held, or back-room, that doesn't process XML sometimes. This is a good thing, because it shows that information can be packaged and transmitted and used in a way that's independent of the kinds of computer and software that are involved. XML won't be the last neutral information-wrapping system; but as the first, it's done very well.
