The actors must be a non-empty subset of the contract stakeholders.
The actors are determined dynamically as follows: if the fetch appears in an update block of a choice
`ch` on a contract `c1`, and the fetched contract ID resolves to a contract `c2`, then the actors are defined as the
intersection of (1) the signatories of `c1` union the controllers of `ch` with (2) the stakeholders of `c2`.
intersection of (1) the controllers of `ch` with (2) the stakeholders of `c2`.

A :ref:`fetchbykey` statement also produces a **Fetch** action with the actors determined in the same way.
A :ref:`lookupbykey` statement that finds a contract also translates into a **Fetch** action, but all maintainers of the key are the actors.
