Hello Brian, Thank you for this review! I have added text to clarify the formatting of these parameters and claims when used in JSON-based interactions. More comments inline.

A JSON string that's the profile name (though 5.6.4.3 maybe prohibits that)? A JSON number that's an integer matching the CBOR Value? Something else? [LS] For JSON the string representation is ok, I reworded 5.6.4.3 to clarify this. Is the value of "exi" in a JWT a JSON number? Seems likely but it's something that should probably be made explicit. [LS] Now explicit Also for "exi", the requirement in 5.8.3. to "keep track of the identifiers of tokens containing the "exi" claim that have expired (in order to avoid accepting them again)" seems problematic in that it sounds like it's mandating an unbounded growth of memory use. Section 6.6. proposes a mitigation for the unbounded growth of memory use problem. Does that resolve your reservations? The draft says that the "cnonce" claim (value) uses binary encoding. What does that mean for JSON based JWT? [LS] Now Base64 encoded binary for JSON.
