    <column name="keypart3"/>

Answer 1

i figured it out.

class JoinedSubclassMapping : JoinedSubclassMapping<Subclass>
{
    public JoinedSubclassMapping()
    {
        Key(key =>
        {
            key.Columns(c => c.Name("keypart1"), c => c.Name("keypart2"), c => c.Name("keypart3"));
        });
    }
}
