Since there already are software implementing descriptors, I don't think we can do this. I'm not sure about making "'" a SHOULD either. > - Calculate the checksum over s/(h|H)/'/ (again, I know that's > complicated with descriptors already widely used) This has been discussed in the past and the conclusion was that the checksum should be strictly over the string itself. This would allow for dumb checksum checkers which don't have to be able to parse descriptors in order to check the checksum.
