    Write a function that validates a patient's risk assessment ID number by ensuring that for each risk factor score (0-9) in the ID, the frequency of that score's occurrence does not exceed the score value itself. For example, in a valid ID, the score 2 should not appear more than 2 times, and the score 1 should not appear more than once, as this would invalidate the hospital's risk assessment model.
