Hi,

Does anyone know of a reason to use RFC 5878?  Extension data can
already be sent in TLS handshakes:

Client -> Server : ClientHello Extension
Client <- Server : ServerHello Extension
Client -> Server : SupplementalData (RFC 4680)


5878 just adds another extension structure inside existing ones:

Client -> Server : ClientHello Extension signalling AuthorizationData
Client <- Server : ServerHello Extension signalling AuthorizationData,
                            SupplementalData containing AuthorizationData
Client -> Server : SupplementalData containing AuthorizationData


Seems like a bunch of added parsing for nothing?  What is this for?
