This will require editing for every new property we add. If this is unavoidable (or unavoidable without additional work you didn't plan to do currently), then a comment to the effect that this has to be edited as well as the dafext.xsd is in order. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
