I missed Patrick's presentation at the ccNSO tech day, but did read the
draft that he circulated a while ago.

>From my perspective, the main problem with how the implementations have
evolved is a loss of interoperability. IIRC, in the case of CZNIC, complete
schemas were defined to replace the standard domain and contact mappings,
reducing EPP into not much more than a framing protocol. Not sure exactly
the rationale for doing that, though I'm sure considerable thoughts have
been put into it. It does mean that registrars could not easily reuse
existing libraries or code written for one registries to talk to another
though.

See above. Also, I believe there are some minor tweaks that could be done to
the existing schema that would make less inherent assumptions about the
registry data model (by making some fields optional). However, I don't any
way to handle schema changes in a backwards compatible manner.

Working along the lines of defining new mapping encompassing common use
cases would perhaps be worth pursuing and more productive than attempting to
change the core protocol. Patrick's work would certainly come in handy in
that case.
