Final prevents Doctrine Embeddable with annotations to work

[ste93cry]

I'm trying to use your library with Doctrine 2.5 embeddable objects. Unfortunately, this is impossible because I'm using annotations instead of YAML and the docblock must be applied to the properties. I can't extend the class to do it because you marked it as final. I know there has already been a long discussion about why you decided to restrict users from inheriting the Money class, but this makes this whole library unusable for anyone using annotations (that are really common on Symfony).

I am trying to realise exactly the same.
My entities all use annotations, and I don't know how to register the Money\Money type.

I have this in my entity:

 /**
 * @ORM\Column(type="decimal", precision=20, scale=2)
 * #@ORM\Embedded(class="Money\Money")
 */
private $value;

and in my config.yml

doctrine:
    dbal:
        types:
            EnumIntervalType: AppBundle\DBAL\Types\EnumIntervalType
            EnumActionType: AppBundle\DBAL\Types\EnumActionType
            Money\Money:
                type: embeddable
                fields:
                    amount: { type: decimal, precision: 10, scale: 2 }
                embedded:
                    currency:
                        class: Money\Currency
            Money\Currency:
                type: embeddable
                fields:
                    code: { type: string, length: 3 }

However, this is not an accepted configuration, I get

Unrecognized options "type, fields, embedded" under "doctrine.dbal.types.Money\Money"
