[odb-users] Relationships and constraints without pointers

Let's say I have these 2 hypothetical objects:

struct Object1
    std::set<std::string> values;

struct Object2
    std::set<std::string> values;

Is it possible for me to create a relationship and constraints using
pragmas and no additional objects or pointers such that the values in
Object2::values can only be those in Object1::values and that
Object2::values is updated when a value is removed from Object1::values or
when the value is changed?
