I didn't know that this was discussed already. In respect to option 3 I really think that if EAI support shall be specific to object types then it would be better to release updated specifications of these objects, maybe with new URIs if necessary. This would be my general preference, as I noted in my previous e-mail. Having extensions that influence the interpretation of certain elements in objects or other extensions has the problem that it increases the complexity over time, makes it less understandable and makes it more difficult to get rid of old stuff. The DNSSEC extensions (1.0 and 1.1) are a good counter example for how it should work. I guess that nowadays no active EPP server or client is unable to use version 1.1, thus 1.0 support could be theoretically removed from the implementations. Maybe one could find additional improvements to the contact object to justify an update. For example, fixing the disclosure settings. While their use have become questionable in the context of data protection regulations like the GDPR anyway, they have the slight design problem that one cannot set and remove specific disclosure settings at the same time. Or one could consider to add a language field, which could be helpful when sending e-mails to registrants, e.g. WDRP e-mails, transfer related e-mails. Maybe there are other aspects with which registrars, resellers and end users are unhappy. Regards, Klaus
