No.  That is not it's purpose, nor should it ever be used in that manner.

ComponentSelector.  ComponentSelector was designed for this purpose.

Per the Developer's docs, if you use a selector, append the "Selector"
designator to the role name:

ComponentSelector selector = (ComponentSelector) manager.lookup( Resource.ROLE + "Selector"
Resource resource = selector.select( hint );

The hint can be any object (a Locale object if you wish, or any string).
