You can call it "in an interoperable fashion", if you prefer that. The IETF is all about interoperability, even though the security area is known (and frowned upon) for providing the most feature-rich set of policy options with the purpose of breaking^H^H^H^H^H^H^H^H limiting or "constraining" interoperability. It refers to interoperability where at least one of the TLS peers implements one of the existing protocol SSLv3 or TLSv1.0->1.2 but not the TLS extension RI update. Providing the interoperability in the protocol is the task of the IETF TLS WG, implementing interoperability with the installed base correctly is the task for the TLS implementor, and deciding and configuring whether interoperability with old peers on renegotiation handshakes is necessary, is the task of the consumer of the technology (configurable policy options). -Martin
