For optimization applications I need the structural information, if outputs of a model exchange FMU directly depend on tunable parameters.

Use Case: FMU outputs in cost functions or constraints of an optimization problem. Derivative based algorithms need to know, if there are direct dependencies on optimization variables (tunable parameters).

Reading the FMI Spec, there seems to be something missing. On page 58 tunable parameters are listed, just as I would expect it:

(𝐲𝑐, 𝐲𝑑) ≔ 𝐟𝑜𝑢𝑡𝑝𝑢𝑡(𝐱𝑐, 𝒖𝑐, 𝒖𝑑, 𝑡, 𝒑𝑡𝑢𝑛𝑒)

But on page 61 in the description of the attribute "dependencies", tunable parameters are not listed anymore.

Is there a reason for it?
