Validation tasks require prediction attribute?

The Self-Organising Map operator does not generate a Prediction attribute, so therefore it cannot be used in validation tasks? Is there another way to achieve some sort of performance evaluation?

The SOM does return a Preprocessing Model, but I'm not sure how this can be used if I want to map new data to the trained SOM. Can anyone provide an example? I can provide a data set if that's required.
