             It is also possible to have fields that reference a set of node entities (1:N). These fields come in
             two forms, modifiable or read-only. Modifiable fields are of the type <code>java.util.Set&lt;T></code>,
             and read-only fields are <code>java.lang.Iterable&lt;T></code>, where T is a @NodeEntity-annotated
