The cord-set rating is determined by the equipment's rating. The cord-set rating cannot be used to determine power requirements. The plug on the cord-set will limit the user to a specific range of mains ratings (and is marked with rating), but is not intended to indicate any specific performance of the mains-connected equipment.
But your original question is valid - who reads and understands these labels? Mostly people like you and me? An electrician doing the repair or install? A fire inspector? But probably not the consumer.

Doesn't answer my questions. The plug provided with the equipment completely answers the 60950-1 requirement without any marking! The end-user installs the equipment using the supplied plug, without reference to the rating markings.
