| michael@0 | 12 | * If a channel implements this interface, the execution of the program in |
| michael@0 | 13 | * question will be restricted in the following ways: |
| michael@0 | 14 | * |
| michael@0 | 15 | * - If the channel does not have an owner principal, the program will not be |

| michael@0 | 17 | * circumstance we have no way to tell whether script execution is allowed at |
| michael@0 | 18 | * all for the originating security context of this channel. |
| michael@0 | 19 | * - If the channel has an owner principal, how it is executed is controlled by |
| michael@0 | 20 | * this interface. However if the owner principal does not subsume the |
| michael@0 | 21 | * principal of the environment in which the program is to be executed the |
| michael@0 | 22 | * execution will be forced to happen in a sandbox. |
