Anonymous Services

..note::

137+
Anonymous services are currently only supported by the XML configuration format.
138+
139+
In some cases, you may want to limit access to a service outside of its
140+
intended scope. This is useful when you want to prevent other services from
141+
using the service as their own dependency. This can be achieved by creating an
142+
*anonymous service*.
143+
144+
For Symfony, an anonymous service is nothing more than a service without a
145+
identifying name which is defined directly in its use context. The following
146+
example shows how an anonymous service can be injected into another service:
