    Write a function that validates a patient's composite health score by ensuring that for each severity level (0-9) in the score, the frequency of that level's occurrence does not exceed the maximum threshold indicated by the level itself. For example, in a score where severity level 2 appears three times, the score would be invalid since 3 exceeds the maximum allowable frequency of 2.
