The human-readable, service-specific name used to represent the PersonaStore to the user.
For example: foo@@xmpp.example.org.
This should be used whenever the user needs to be presented with a familiar, service-specific name. For instance, in a prompt for the user to select a specific IM account from which to initiate a chat.
This is not guaranteed to be unique even within this PersonaStore's Backend. Its value may change throughout the life of the store.
