Yep and worse they did not address in a satisfactory manner domain definitions. That I can tell you for sure. You can not have a good RM implementation without a proper domain support.

Are you suggesting it's a regression. I do personally believe so.

Can we really speak of innovation? I think things are getting worse everyday and I tell you that from experience. The whole idea about implementing XML structure in dat management is a mess and brings us back 30 years in past (hierarchical model), All what RM was supposed to cure.
