Hardie Expires October 29, 2016 [Page 1] Internet-Draft RFC6455 IANA clarification April 2016 1. Introduction [RFC6455] section 11.5 sets up a Subprotocol Name Registry at IANA and directs IANA to use First Come First Serve registration procedures as set out in [RFC5226]. The reuse of this registry by other protocols has indicated that some clarification of the instructions to IANA would be useful. 2. Clarified instructions The tokens registered in the Websockets sub-protocol registry created by RFC 6455 Section 11.5 are matched using case-sensitive string match. IANA is, however, instructed to decline registrations in the registry which differ only as to case, in order to minimize potential confusion among different registered versions. For other useful advice on avoiding collision, registrants are encouraged to consult the non-normative section 1.9 of RFC 6455. 3. Security Considerations This document describes an update to registry policy, not a protocol. 4. IANA Considerations This document is, in its entirety, a clarification of the registry policy for the Websockets sub-protocol name registry. 5.
