 ``remove_empty_tags``
    If set to true, removes all empty tags in the generated XML.

 Handling Constructor Arguments
 ------------------------------

 If the constructor of a class defines arguments, as usually happens with
 `Value Objects`_, the serializer won't be able to create the object if some
 arguments are missing. In those cases, use the ``default_constructor_arguments``
 context option::

    use Symfony\Component\Serializer\Serializer;
    use Symfony\Component\Serializer\Normalizer\ObjectNormalizer;

    class MyObj
    {
        private $foo;
        private $bar;

        public function __construct($foo, $bar)
        {
            $this->foo = $foo;
            $this->bar = $bar;
        }
    }

    $normalizer = new ObjectNormalizer($classMetadataFactory);
    $serializer = new Serializer(array($normalizer));

    $data = $serializer->denormalize(
        array('foo' => 'Hello'),
        'MyObj',
        array('default_constructor_arguments' => array(
            'MyObj' => array('foo' => '', 'bar' => ''),
        )
    ));
    // $data = new MyObj('Hello', '');

It's not exact: the serializer deals well with constructor arguments, if they are present in the data to deserialize. The`default_constructor_arguments` is useful only when the value has not been provided in the data to deserialize. Nek- reacted with thumbs up emoji
