The SKOS Reference [1] Section 7.1 says:
[[
The Simple Knowledge Organization System distinguishes between two
basic categories of semantic relation: hierarchical and associative.
A hierarchical link between two conceptual resources indicates that
one is in some way more general ("broader") than the other ("narrower").
]]
skos:broader might be used to represent part-whole or instance
relationships, which aren't strictly sub/super set, e.g. from [2]:
fairy tales
Cinderella
Rumpelstiltskin
nervous system
central nervous system
brain
armies
divisions (military)
battalions
regiments
Cheers,
Sean
