Yes, although it's based on theoretical work, not real-world experience.
XML Schemas are designed to model XML documents, not objects.
Consequently, you get some weirdnesses when trying to map the schema
data model to an object model. If your application really thinks in
terms of objects, better to start with an object/generic modelling
language and go the other direction. That way, the XML schema is just a
serialization syntax, not a model.
