Someone should file a "wishlist" bug report on this, as it has been requested
a couple of times.

There would be ways to approach this. One is the "generateDS" tool by Dave
Kuhlman:

we could try to extract the parser (or reimplement it with lxml) and run an
annotation instead of the class generation step.

We could also look a bit deeper into the internal handling of XML schema in
libxml2, there could be something to start from.
