Apologies Pieter, this fell "below the fold" in my inbox so to speak and I lost track of responding to it. Thanks for the proposed new "notes" for the errata, which I do think are sufficient now. In conjunction with that simple "corrected text" you had of "5. Verify the resulting JOSE Header according to RFC7515 or RFC7516."
