This post is more or less and addendum to my post on Sovereignty Demystified in that everything explained in this earlier post except the association between a Connection and its property of sovereignty still applies.
In Clique Space, sovereignty is a feature only of the Identity Element. Sovereignty is never communicated directly between Client Devices, but one device can work out if an Identity informed to it by a neighbouring device is indeed sovereign when it receives an Identity's key feature. The given Identity is sovereign when the Identity can be used to generate the same public key that was given as the key in the feature. In this case, the corresponding public/private key pair are stored as a CoSovereignKey in the given Identity.
A Client Device can use an Identity with a non-null CoSovereignKey (a sovereign Identity) to sign deliberations that it generates when informing other Client Devices of subscriptions. Subscriptions are associations between a given feature Element, qualia known as the sense datum and the subject, and a given subscription tag - either an Identity if the subscription is a challenge, or a belief (an association between two Identities - the claimant and the candidate) if the subscription is a message.
Because an Identity has to be sovereign to contain a private key, sovereign Identities are the only type of Identity capable of generating signatures for deliberations.
Sovereignty encompasses an individual's concept of self-hood. Identity is a projection of this self-hood within an individual's manifest Clique Space and outward to Clique Spaces that manifest other individuals.
