To fix this, make sure the tag has exactly 1 value.
Example
The Car stereotype contains a tag definition gearTransmission with the multiplicity set to one. The class Sedan with the applied stereotype Car does not have the gearTransmission tag specified with a value, which causes an error. The error is resolved by specifying the gearTransmission tag with a value.
