list and set are not natively supported field types in the ROS msg idl.

Unbouned arrays would probably be equivalent to a list.

I don't think there is a way to get set semantics (ie: collections with a uniqueness guarantee on items) without user-level code (ie: msg producer and consumer) enforcing that.
