Two comments:

- Obviously, inactive can be in <candidate> and I would not rule out
  that inactive configuration can be in any other or future
  configuration datastores.

- Whether protocols support inactive or not does not belong into a
  definition of what inactive configuration is. The same for backwards
  compatibility considerations etc.

So if we define inactive configuration, the definition should be
something like this:

* inactive configuration: Configuration held in a configuration
  datastore that is marked to be inactive. Inactive configuration is
  ignored during validation and never applied and actively used by
  a device.

Yes, we should use 'inactive configuration' everywhere to be consistent.
