I don't get the distinction. As soon as you've got a graph you've got a
tree (or perhaps many trees).

Sure, but with an XML representation of a graph you're back to the

exchanged a graph, you've exchanged something that, given enough extra
knowledge, someone else might be able to build a graph out of.
