This annotation defines an attribute in open MBean (ManagedObject) or
CompositeData (ManagedData).  It is useful in cases where the parent class
cannot be annotated (for example, Object.toString(), or a framework class
that must be extended
but cannot be modified).  The attribute id is defined in the annotation, and
it is implemented by the methods inherited by the Managed entity.

An example of a use of this is to handle @ManagedData that inherits from
Collection, and it is desired to display a read-only attribute containing
the elements of the Collection.  Simple add the annotation

 methodName="iterator" )

to handle this case.  Note that this only supports read-only attributes.
