Hi Jürgen,

I do not know how it could be implemented, but I understand the new YANG module versioning may lead to this kind of scenarios. For example, a server implementing two revisions of the same module, one of them introducing breaking changes. Not sure if we may find such use cases, but my point was that YANG Push should be able to support them if needed.

This said, I agree with you that the new YANG module versioning may trigger a cascade of extensions in many different areas, such as YANG library or NETCONF get operations as Andy pointed out. We may just hit a topic that will require a broader discussion across WGs.

Many thanks,

Best regards,
Nacho.

I think Andy's question was how it is possible to implements multiple
module revisions. Can you answer this?
