+ *
+ * Example usage with default_values configuration:
+ * @code
+ * destination:
+ *   plugin: 'entity:node'
+ * process:
+ *   type:
+ *     plugin: default_value
+ *     default_value: page
+ *   field_tags:
+ *     plugin: entity_generate
+ *     source: tags
+ *     default_values:
+ *       description: Stub description
+ *       field_long_description: Stub long description
