This refers common bindings, so this is preferred for
unevaluatedProperties instead of additionalProperties.

Yes and no. If you want to define specific common properties are used 
(and not used), then listing them in the specific schema with 
'additionalProperties' is the right way to do that. If all properties in 
the referenced schema are valid, then unevaluatedProperties is correct.

If we wanted using unevaluatedProperties to be a hard rule, we could 
make the meta-schema enforce that.

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.

Thank you,
