              New user IDs that the sending server would like to subscribe to the
              presence of. The sending server should not include users it has already
              requested to be subscribed to.

              The receiving server should ensure the sending server has reasonable
              interest in subscribing to the provided users. The receiver may ignore 
              a request to subscribe to a user the sender does not have reasonable
              interest in. Reasonable interest may be residing in a room with the user,
              being subscribed to a presence list, or some other requirement.

              If non-empty, the receiving server should immediately send the presence
              updates to the sender for the users requested.

              type: string

            type: array
            description: |-
              New user IDs the sending server is no longer interested in receiving
              presence updates for. The sending server should not include users it
              has previously requested to be unsubscribed from.
