They are never mandatory, in the sense of the overall tag being invalid
without them.

For guidelines on when they are recommended, see RFC 5646, Section 4.1,
"Choice of Language Tag." The whole section is worth reading, but one of
its main points is to avoid using extra subtags when they are not
needed. So you might use "kea-barla" when it is important to distinguish
Barlavento from Sotavento (as in your project), but not when
distinguishing it from Portuguese.
