- To fix this, make sure the number of values defined for a tag does not exceed the number defined for the stereotype's tag definition multiplicity.

The Car stereotype contains a tag definition gearTransmission with the multiplicity set to one. The class Sedan with the applied stereotype Car has the gearTransmission tag specified with two values, which causes an error.
The error is resolved by removing one of the values.
