I understand that having a reference to a common schema isn't a direct reason
to replace with unevaluatedProperties because it depends on how each property
of the common schema is handled in this schema.

Since there is no property to evaluate with "if" etc., I think that it can
be left as "additionalProperties" in this schema.
I withdraw this patch.

At the moment it is difficult to decide it to be a hard rule.
