Hi,

think of a business solution application, e.g. managing technical products 
with different physical specifications (working on something like that ;-), 
highly customizable CRM/ERP or whatever...

Three use-cases for xml based external validation definition (not to mention 
again client-side validation etc.)

1. Have a non java programming consultant install and customize the 
application for different clients
2. Have the client / user administer validations himself, without needing to 
know java, without the need to rebuild, documentable in user guide
3. Providing customizable closed source (if someone likes to...)

More reasons needed ? :)

Regards,
- Rene
