| 11 * | |
| 12 * If a channel implements this interface, the execution of the program in | |
| 13 * question will be restricted in the following ways: | |
| 14 * | |
| 15 * - If the channel does not have an owner principal, the program will not be | |
| 16 * executed at all, no matter what. This is necessary because in this | |
| 17 * circumstance we have no way to tell whether script execution is allowed at | |
| 18 * all for the originating security context of this channel. | |
| 19 * - If the channel has an owner principal, how it is executed is controlled by | |
| 20 * this interface. However if the owner principal does not subsume the | |
| 21 * principal of the environment in which the program is to be executed the | |
| 22 * execution will be forced to happen in a sandbox. | |
