The Platform spec explicitly states that in addition to the two types
listed in the table that you cite, the following may also be specified
by means of resource-env-ref: Validator, ValidatorFactory,
ManagedExecutorService, ManagedScheduledExecutorService,
ManagedThreadFactory, ContextService, BeanManager.
A resource-env-ref may also be used to specify a JMS Destination,
although message-destination-ref is preferred for this purpose.

The Common Annotations spec section 2.3 and table 2.4 still refer to
the state as of Java EE 5, so we should update it to reflect these
additions when we next do an MR.
