Collection

Collections are a way to represent paginated groups of entities. They are used everywhere lists of entities can be found, such as a user's outbox.

Pages should be limited to a reasonable number of entities, such as 20 or 80.

As Collections are independent and not part of a larger entity (like ContentFormat), they should have a valid Signature.
