Plus, of course, the child object can add a new method which gives access to
the new data model, and this method will be used by callers that rely on the
new schema.
That's why I believe OOP can provide useful insights in bringing the X to
XML.

No argument from me about this. Remember, though, that we can remove
structures that are in ancestor types and elements when we derive new ones -
XML Schema supports doing so, for example - which we can't with standard OO
methodologies. In this way, XML markup can be considered richer than OO
modeling.
