DMN12 — Different definition of hit policy collect aggregations in FEEL and DMN

On page 83 for DMN: "the result of the decision table is the sum of all the distinct outputs"
On page 137 for FEEL built-in function: "return the sum of the outputs"

Same applies to count aggregation.

Why does a DMN decision table only aggregates distinct values, but a FEEL built-in function does not?

Is this difference between the DMN Decision Table in chapter 8 and the FEEL built-in function in chapter 10 the intended meaning?

remove 'distinct' from hit policy aggregation definitions
