+   * this entity itself, a configuration change (whether related to this entity,
+   * another entity, or non-entity configuration), you need to check and see if
+   * this entity change is part of a synchronization process, and skip executing
+   * your code if that is the case.
+   *
+   * For example, \Drupal\node\Entity\NodeType::postSave() adds the default body
+   * field to newly created node type configuration entities, which is a
+   * configuration change. You would not want this code to run during an import,
+   * because imported entities were already given the body field when they were
+   * originally created, and the imported configuration includes all of their
+   * currently-configured fields. On the other hand,
+   * \Drupal\field\Entity\FieldStorageConfig::preSave() and the methods it calls
+   * make sure that the storage tables are created or updated for the field
+   * storage configuration entity, which is not a configuration change, and it
+   * must be done whether due to an import or not. So, the first method should
+   * check $entity->isSyncing() and skip executing if it returns TRUE, and the
+   * second should not perform this check.
+   *
+   * @return bool
+   *   TRUE if the configuration entity is being created, updated, or deleted
+   *   through a synchronization process.
