 * well utilized, this is due to our special handling of the serialization process of property
 * mappings, we decided to only serialize property mappings relevant to its parent class mapping
 * e.g. for PureInstanceSetImplementation, we would only serialize PurePropertyMapping and the rest

 * But we added this here so we are ready in case in the future we change our strategy of handling
