| * the host will not need to modify the default values used by SLPC. |
| * SLPC remembers the default values which allows the host to easily restore |
| * them by simply unsetting the override. The host can set or unset override |
| * parameters during SLPC (re-)initialization using the SLPC Reset event. |
| * The host can also set or unset override parameters on the fly using the |
| * Parameter Set and Parameter Unset events |
