Shepherd writeup

Technical Summary

   This document clarifies the instructions to IANA for the sub-protocol
   registry set up for Websockets in RFC 6455.

Working Group Summary

   The reason for concerns being raised was that the registry is being reused
   by the RTCWEB WG's datachannel protocol.

   This is not a WG document, however it was discussed on the HYBI mailing list
   where RFC 6455 was discussed, as well as on the RTCWEB WG list.
   There is the HYBI mailing list consensus behind this draft.

Document Quality

   Implementors of WebSocket specification (RFC 6455) commented on this proposal and support it.
   This document is purely about IANA procedure and it doesn't require any changes to existing implementations.
