Re: [6tisch] Adding CCA to the terminology draft

[Thomas Watteyne <[e-mail]>]

Thanks Maria Rita for agreeing to add the term. Can I ask you to do the

About last call, while I agree with the definitions in there, we MAY want
to remove some, or at least do a sanity check. Maria Rita, could I ask you
to go through the list and make some recommendations?
