9 # * A credential is a set of privileges or a Ticket, each with a flag
10 # to indicate delegation is permitted.
11 # * A credential is signed and the signature included in the body of the
13 # * To support delegation, a credential will include its parent, and that
14 # blob will be signed. So, there will be multiple signatures in the
15 # document, each with a reference to the credential it signs.
