/**
* Marks an injected parameter to be destroyed after invocation.
*
* When a constructor or a method is annotated with {@link javax.inject.Inject},
* its parameters may be annotated with \@TransientReference.
* If a parameter is annotated with \@TransientReference
* and the injected bean is {@link javax.enterprise.context.Dependent}-scoped,
* it may be destroyed by the container right after the invocation
* of the constructor or method.
*
* Technically spoken, the parameter will not be added to the
* {@link javax.enterprise.context.spi.CreationalContext}
* of the bean of the constructor or method, but will be created with a separate
* {@link javax.enterprise.context.spi.CreationalContext}
* that will be destroyed after the invocation.
