ServletPolicyList (Vitro API 1.12.1 API)

```
public class ServletPolicyList
extends Object
```
This maintains a PolicyList in the ServletContext. As a rule, however, this is only used as the basis for the RequestPolicyList. Client code that wants to access the current list of policies should look there.
