| * If an IDL method signature has an IDL {@code any} as an "out" |

| * parameter in the method invocation; for "inout" parameters, the programmer |
| * must also fill the "in" value to be sent to the server. |
| * Before the method invocation returns, the ORB will fill in the |
| * value corresponding to the "out" value returned from the server. |
| * <P> |
| * If {@code myAnyHolder} is an instance of {@code AnyHolder}, |
| * the value stored in its {@code value} field can be accessed with |
| * {@code myAnyHolder.value}. |
