 If your constraint validator has dependencies, such as a database connection,
 it will need to be configured as a service in the Dependency Injection
 Container. This service must include the ``validator.constraint_validator``

-As mentioned above, Symfony will automatically look for a class named after

+Now, when Symfony looks for the ``ContainsAlphanumericValidator`` validator, it will
+load this service from the container.
 
-    public function validatedBy()
-    {
-        return 'Fully\Qualified\ConstraintValidator\Class\Name'; // or 'alias_name' if provided
-    }
-
-Make sure to use the 'alias_name' when you have configured your validator as a service. Otherwise your validator class
-will be simply instantiated without your dependencies.
+.. note::
+    In earlier versions of Symfony, the tag required an ``alias`` key (usually set
+    to the class name). This is still allowed your constraint's ``validateBy``
+    method can return this alias (instead of a class name).
