Plans for cascade type of delete orphan in the EJB3 spec?

Out of curiosity, does anyone know if EJB3 is planning on supporting the hibernate delete orphan functionality?

When using EJB3 I'd rather not have to use hibernate annotations if I don't have to (seems more "pure" and more cross-platform).

Having the following is annoying:

Code:

  @OnDelete(action=OnDeleteAction.CASCADE)
  @OneToMany(cascade=CascadeType.ALL, mappedBy="property")
  @JoinColumn(name="folderId")
  @Cascade({org.hibernate.annotations.CascadeType.ALL,
    org.hibernate.annotations.CascadeType.DELETE_ORPHAN})

How does Sun recommend doing this? I tried a uni-directional one-to-many (no many-to-one), and hibernate tried to null my fk instead of deleting the child object.

In the "Enterprise Java Beans 3.0, Early Draft 2" on page 32 is written:

We are considering whether to add an option to cover the removal of orphaned entities involved in parent-child relationships.

So i guess this very important feature is still an open issue.
