James is absolutely correct. We've been doing a Proof-of-Concept with a key goal of separating validation from application or even data layers. Our test case requires lighter validation at the beginning and stronger validation towards the end. The test case is in international freight logistics. Here we have a customer provide initial booking information and then ask an operations person to complete the data set. Our solution is to apply different schemas temporally (at different times within the process) or even dependent on the user role. We are somewhat new to XSDs, but have found them very useful for data typing, setting a field to be non-nillable, etc. Unfortunately, we've not found mechanism to support heuristic validation rules such as a Estimated Time of Arrival must be equal to or less than an Estimated Time of Departure. It would be useful if this type of logic could be embedded within the XSD rather than a piece of Java or even possibly an XSLT. Again, these heuristic validation rules must also be applied temporally.
