Usage Guidelines Messages are sync-data (also known as checkpoint data) sent between two endpoints.
When an ISSU-aware client establishes its session with a peer, an ISSU negotiation takes place. The
ISSU infrastructure uses the registered information to negotiate the capabilities and the message version
to be used during the session.
