What are driving license codes?

What are driving license codes?. In addition to driving-license categories there exist driving-license codes.

These do not refer to vehicles, but rather certain conditions that can be placed on a person’s driving license, for one or many of the class of vehicles they can drive. For example a code might indicate you have to wear corrective glasses or lenses to drive, or that you are an organ donor.
