Cool. Would you be interested in hosting this on
http://jaxb2-commons.dev.java.net/ ?
There has been substantial interest in this. I think other people might
be interested in contributing to this project.

Sure. The basic idea is to look at CPropertyInfo.getSchemaComponent(),
and then determine what facets you want to copy over.
Then use methods on JAnnotatable to put annotations into the generated code.
