Doctrine 2.5 Embeddables

Hi,

I've got a problem dealing with the Embeddable implemented in Doctrine 2.5.
Base on Doctrine documentation we can request the property of an Embeddable like this: "embeddable.property".

So my idea was that we should be able to generate fixture for the property the same way, for exemple:

``` yaml
AcmeBundle\Entity\Object:
email:
adress.city: Paris
```

Here I have Adress as an Embeddable and city one of the property.

Is it a way around in the current version or the functionnality still needs to be developped ?

Thanks for your work.
