 #### (5) Object capability authorization tokens
 
+#### (6) Managing actor
+
+Allows an object to specify which actor manages it. For example, if you'd like
+to send an `Update` activity, or some other activity that targets or modifies
+some object, but that object isn't an actor, how do you know to which actor to
+send it? This proposal proposes to have a dedicated property for this purpose,
+independent of any domain-specific vocabulary or extension.
+
+The current working name for this property is `managedBy`.
