This breaks all validating WSDL clients. Our tools have thousands of clients and such a change affects all of them. Is there any reason for such a breaking change?
Going forward, we can try to make this kind of change more considerate of potential problems with integrations, and we should make them not very frequently, and warn people before we do it.
In terms of Community communication, do you have any suggestions as to how we could reach out to people like you doing this sort of work?
