public List<ShapeId> getIntroducedErrors() {
        return introducedErrors;
    }
Gets the list of common errors introduced by the shape and not
inherited from mixins. These errors can be encountered by every
operation in the service.

Each returned {@link ShapeId} must resolve to a
{@link StructureShape} that is targeted by an error trait; however,
this is only guaranteed after a model is validated.

@return Returns the introduced service errors.
