 #### Direct exchange
 
 The simplest mode of operation is that a pair of controllers, each with their own AID, use their respective applications (including agents when applicable) to directly exchange key event messages that verifiably establish the current key state of their own AID with the other controller. For each exchange of key events, the destination controller acts as a validator of events received from the source controller. Therefore, given any key event, a given entity is either the event's controller or a validator of some other controller's event.

-The Backer Add, `ba` field value is a list of strings that each is the fully qualified AID of a Backer to be appended to the current Backer list. This allows Backer lists to be changed in an incremental fashion. A given AID MUST NOT appear more than once in any Backer Add list. The Backer Add, `ba` list appears in Rotation and Delegated Rotation events. Given such an event, the current backer list is updated by appending in order the AIDs from the Backer Add, `ba` list except for any AIDs that already appear in the current Backer list. The AIDs in the Backer Add, `ba` list MUST NOT be appended until all AIDs in the Backer Add, `ba` list have been removed.
