+        In order to share a set of identity attributes with a third party,
+        re:claimID introduces the concept of "Tickets". A Ticket may be
+        issued by a user for an identity to a relying party.
+        The Ticket may then be used by the relying party to retrieve the
+        shared attributes from the name system.
+        The record wire format of a Ticket is as follows:

+         The TID essentially serves as a shared secret between user and
+         relying party. knowledge of the IDENTITY key and the TID allows
+         the relying party to iteratively query attribute data in GNS.
+         Tickets are stored as RECLAIM_TICKET records under a label derived
+         from the TID by applying a Base64-encoding. In addition to the ticket,
+         the record set also contains references to the shared attributes as
+         well as any credential presentations which attest attribute values.
