> [Qin]: Good point, suppose we have two revisions of a YANG module, one revision is not back-compatible to another, would it be great for device to implement both revisions, but we may also require some fall back mechanism or update mechanism to inform the client some revision of the module is not supported.

The YANG versioning model requires that modules are backwards compatible.
