Items

items is where you will provide the columns you'd like returned from CMR.

If you're querying single objects count is not available and therefore items isn't necessary -- you can simply list the columns you'd like returned from CMR as a direct child of your query.

Note that the response you get will match the structure of your query, meaning that in the event you've requested data from a list query you'll receive the results in an items array whereas with a single query request you will not.
