I don't have time right now to study the webrev but I think the proposal 
(and CSR) looks okay. The only thing is that it's bit awkward that each 
of the possible values to the option are optionally but at least one is 
required. Once jlink is updated to allow for the value to be optional 
then I assume this wart can go away.
