-/**
- * Defines an 'entity_reference_revisions' data type.
- *
- * This serves as 'entity' property of entity reference field items and gets
- * its value set from the parent, i.e. LanguageItem.
- *
- * The plain value of this reference is the entity object, i.e. an instance of
- * \Drupal\Core\Entity\EntityInterface. For setting the value the entity object
- * or the entity ID may be passed.
- *
- * Note that the definition of the referenced entity's type is required, whereas
- * defining referencable entity bundle(s) is optional. A reference defining the
- * type and bundle of the referenced entity can be created as following:
- * @code
- * $definition = \Drupal\Core\Entity\EntityDefinition::create($entity_type)
- *   ->addConstraint('Bundle', $bundle);
- * \Drupal\Core\TypedData\DataReferenceDefinition::create('entity_revision')
- *   ->setTargetDefinition($definition);
- * @endcode
- *
- * @DataType(
- *   id = "entity_revision_reference",
- *   label = @Translation("Entity reference revisions"),
- *   definition_class = "\Drupal\Core\TypedData\DataReferenceDefinition"
- * )
