No, we use XML Schema to describe our business objects whereas Castor
uses its own format. And no, our toollkit doesn't need reflection
because the generated business objects contains all information needed
to be serialized in a performant way.

That's what a toolkit should be able to do. Generate the
XMLizable methods as well out from the XML Schema definition.
