 * Product unique data consists of data that is unique among all the products for a given attribute.
 * Only pim_catalog_identifier, pim_catalog_number, pim_catalog_text and pim_catalog_date attribute types can be
 * defined as unique.
 *
 * For instance, if the attribute "release date" is defined as unique.
 * Then, the data "05/24/1980" can be used only once among all the products.
