|  | The priority order specified for the associated Software.Version, | 
|  | represented as a value between 0 (High) and 127 (Low).  Any value | 
|  | above 127 has implementation-specific purpose. | 
|  |  | 
|  | Only one Software.Version, per associated device, may be at any | 
|  | particular priority.  A requested priority change may cause other | 
|  | Software.Versions to change priority. | 
|  |  | 
|  | A dual-sided redundancy model could be represented by two | 
|  | Software.Version associations, one of which is at priority 0 and the | 
|  | other at priority 1.  When a new image is Activated, the old | 
|  | priority-1 association is deleted, the old priority-0 association | 
|  | becomes priority-1, and the new image is assigned priority-0. | 
|  | # TODO: Specify "EAGAIN" type error when priority is unable to be modified | 
|  | #       due to current system state.  Currently, sdbusplus does not support | 
|  | #       errors on properties. |
