Hi Rory, Thats the whole point.
For the sake of version 1 you keep the extensions optional, but useally they are mandatory for version 2. So IMO by then you are making it difficult and errorprone for nothing. Just keep the webservices apart, so nobody gets hurt. // Ryan -----Original Message----- From: Rory F.

However they will not have to reprogram if they do not want the extended functionality as long as the new xml format only introduces optional elements/attributes.
