  3. 11.x core/modules/serialization/src/Encoder/XmlEncoder.php \Drupal\serialization\Encoder\XmlEncoder

Adds XML support for serializer.

This acts as a wrapper class for Symfony's XmlEncoder so that it is not implementing NormalizationAwareInterface, and can be normalized externally.

@internal This encoder should not be used directly. Rather, use the `serializer` service.
