Ah, okay. I should have said if the directory/container in question 
supports duplicate entries or not. For indices this is generally true, 
for other types, it's not :)

They are actually used by BFS to maintain the index type. Although it 
also duplicates this information in the B+tree header, we now also use 
it to report the types when calling stat() on an index.
