Re: [Iot-directorate] Question on IETF IOT-devices scope

[Toerless Eckert <[e-mail]>]

Nice. Have you checked work around https://tools.ietf.org/html/rfc7460 ?
Maybe thats of interest as well to you. If its missing what you need,
maybe it would still be a good basis to link off any additional information
you think is missing.
