Schematron + xPath 2.0 is extremely powerful. In fact, one could argue that it can do everything that XML Schema (or RelaxNG) can do, plus a lot more.
For example, below is an XML document showing information about an aircraft and vertical obstructions on its flight path. One critical operational constraint is:
"Check that the aircraft's altitude is at least 500 feet above all the vertical obstructions"
If you are using XML and a validation tool to work out if there is an obstruction in the way of an aircraft then you might find the aircraft has hit it before the result has been returned...
