Yes, I don't see any problem with that. I consists of "km" "/" and "s", 
where "km" consists of the prefix "k" and the unit "m". It is legal 
accordig to the rules-to-be above. What problem do you see with it ?

BTW, it doesn't matter much what you and I thinks about this. The one
who writes the parser usually decides. Are you volunteering?
