NSCollectionView under the hood?

There have been a few posts on the list voicing confusion with the way 
NSCollectionView works. I am also trying to subclass it, and have 
found the documentation to be quite opaque. What's an item prototype? 
What does it do? What's the deal with NSCollectionViewItem? How does 
any of this relate to the item's representedObject?

Is the documentation vague because we're not really supposed to be 
subclassing NSCollectionView? Or is it built around some pattern I'm 
not familiar with so I'm not cluing in to obvious naming conventions 
or something? It seems like it can be made into a powerful control 
(it's used as the basis for IKImageBrowserView?), and I'd really like 
to make use of it in my code if I could just figure out how to connect 
the plumbing.
