Description Christian Damus

Transaction API needs to provide a way for clients to register a file notification validator that will always be executed at the commit phase of a transaction (after pre-commit) and that has the ability to cause a transaction to roll-back.

This is needed to handle changes made to resources during the course of a transaction by Adapters (trigger listeners using the ResourceSetListener API can perform their own validation).

Obviously, the base Transaction API cannot actually implement workspace validate-edit, but will need to provide an additional hook in the commit phase of a Transaction.  Consider implementing a default validate-edit capability (using the appropriate workspace API) in the Workspace integration layer.
