[odb-users] One-to-many relationship in composite primary key

I have two entities, school and class. School has a simple primary key (id), while class has a primary key composed by a name and a reference to its school.
In SQL terms:
CREATE TABLE school (
id BIGINT NOT NULL PRIMARY KEY
CREATE TABLE class (
school_fk BIGINT NOT NULL REFERENCES school (id),
name VARCHAR (30) NOT NULL,
PRIMARY KEY (school_fk, name)
How can I implement this with ODB?
Section 7.2.1 of the manual states that a composite value type cannot have any object pointers, is this a thing that ODB can't do?
Thanks for the help.
