Another option would be to create a ModelRegistry and then have you functions import that and grab the classes off of there.
But I think bound metadata may be what you want. It might be worth documenting that use case better, but I'm pretty swamped at the moment. Hopefully somebody can step up and help out... --Mark Ramm On Wed, May 27, 2009 at 10:06 PM, Uwe C.
