If the DataMapper shall map a 1:N relation for
a property of a domain object and the element
type of this property is another domain object
and not a storage type, the data mapper must
always fetch the related elements from persistence
and cannot rely on the persistence session lookup.

This is the case because the relation to the parent
is set on the child side and not the other way around.
The column in the parent row is useless in that case
and does not hold the id of the child.

We can also not rely on the persistence session
because we do not know the identifier of the child
until we fetched it.
