translated - all custom properties will automatically be fetched from their translated record on the database. This means
you don't have to explicitly mark any custom properties as being translatable.
The `[api:Translatable]` decorator applies only to the getCMSFields() method on DataObject or SiteTree, not to any fields
added in overloaded getCMSFields() implementations. See Translatable->updateCMSFields() for details. By default, custom

attach this behaviour to custom fields by using Translatable_Transformation as shown below.
