3.2.5.1 Register
The service MUST create a new registration record using the PeerNodeAddress structure that is contained in the Register message and MUST assign the new record a unique RegistrationId element. The service MUST then send a RegisterResponse message to the client with the newly created RegistrationId and a RegistrationLifetime element with the value of "DefaultRegistrationLifetime". If any error occurs during the processing of the Register operation, the connection with the resolver client MUST be aborted immediately.
