I'm certainly not going to argue with you over the limitations of XSD. What you can express in terms of schema simpleType restrictions is limited, and some of the options are ugly (especially regular expressions!). And yes, in essentially every non-trivial case you still need to perform business-level validation of documents even after you've schema-validated them. > ... > Very important points.

There are many (and more all the time) complex XML schemas in use by various industries, and having both JavaDocs that describe the restrictions on particular values (for your IDE) and immediate error reporting when you set a value incorrectly at runtime would be a powerful aid to working with these schemas. - Dennis ------------------------------------------------------------------------------ Special Offer-- Download ArcSight Logger for FREE (a $49 USD value)!
