True. But actually that's confusing as well IMO. Why not (re-)use "item"? ListItem is basically an indirection/proxy/wrapper for the entity you want to add to the list. It uses "item" to reference that entity. Couldn't we use item directly on ItemList as well? If not, probably it would still be better to use "item" on ItemList and change ListItem's "item" to "value" or something similar.

I quite like the flexibility of having both next/previous and itemPosition. I just wonder what happens if they contradict each other (caching could easily lead to such situations). Should consumers reject such data? Or should one of the two mechanisms (probably itemPosition) be ignored in such cases?
