Technically your 1:1 are really 1 to many because 1:(0or1) is implemented in practice as a 1 to many inthat order. The set/notice is in theory a many-to-many which is more normally implemented as member -< member-notice >- notice with member-notice as the link table, so that the "set" is really a view on member-notice for a given notice.

What I'd be doing about sets is making a container object "set" that requires an instance variable to have a particular notice filled in so it can go retrieve all member-notice pairs for that notice, thereby populating the container class.
