Maybe the serializer should also allow the legal literals {1, 0} for booleans

[slopjong]

SimpleXML is using 1 and 0 for booleans but the JMS serializer doesn't accept these literals. Is there a reason why only the canonical representation is supported?

...
$dom = new \SimpleXMLElement($xml);
$dom->aboolean = true;
$xml = $dom->saveXML();
...

// an instance of the JMS serializer
$deserializer->deserialize($xml, 'My\Model');

 JMS\Serializer\Exception\RuntimeException
 Could not convert data to boolean. Expected "true", or "false", but got "1".
