+/**
+ * Base destination class for importing configuration entities.
+ *
+ * Available configuration keys:
+ * - translations: (optional) Boolean, if TRUE, the destination will be
+ * associated with the langcode provided by the source plugin. Defaults to
+ * FALSE.
+ *
+ * Examples:
+ *
+ * @code
+ * source:
+ * plugin: d7_block_custom
+ * process:
+ * id: bid
+ * info: info
+ * langcode: language
+ * body: body
+ * destination:
+ * plugin: entity:block
+ * @endcode
+ *
+ * This will save the migrated, processed row as a block config entity.
+ *
+ * @code
+ * source:
+ * plugin: d6_i18n_profile_field
+ * constants:
+ * entity_type: user
+ * bundle: user
+ * process:
+ * langcode: language
+ * entity_type: 'constants/entity_type'
+ * bundle: 'constants/bundle'
+ * field_name: name
+ * ...
+ * translation: translation
+ * destination:
+ * plugin: entity:field_config
+ * translations: true
+ * @endcode
+ *
+ * Because the translations configuration is set to "true", this will save the
+ * migrated, processed row to a "field_config" entity associated with the
+ * designated langcode.
