I'd like to request that object archiving be implemented for the Knowledge Bank.  Although a version history of the object is kept, as soon as an object is deleted/removed from an article, it's lost forever. 

I'm frequently finding that, when new documents are brought in to replace the old, the old are deleted.  If we're using the Knowledge Bank as the primary storage for these documents (which is implied as the version history is kept), having an Archive ability would ensure that no previous information is lost.
