No, I'm suggesting that the annotations become an independent Commons component.
If we don't want these used outside Commons (probably a good idea)
then we can make this clear through Javadoc and package naming etc.

The alternative is to add them to every component as and when they
want to use them.
And again, we should probably try to prevent them being used externally.

My position is that only adding them to LANG is not the best solution.
