When an element has several sub-elements, which ones require element eligiblity?

Summary:

Some types of element have several additional sub-elements. Which of these sub-elements require eligibility?

Content (required):

For example, when you create an annual leave element, HCM creates a long list of additional elements, see below.

The base element will require eligibility, and any results elements that need to be costed will too.

What about the others? Calculator, Distributor, Accrual, Entitlement, Disbursement, etc. It's very tempting to just HDL load open eligibility on the whole lot, and that seems to work, but should we be more selective than that?
