I've updated the text to use "h".

Since there already are software implementing descriptors, I don't think
we can do this. I'm not sure about making "'" a SHOULD either.

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.
