There is one substantive issue identified below to address in the
draft.  The rest are editorial.

Section 1 (Introduction):  Change “the registry created by [RFC8747
<https://www.ietf.org/archive/id/draft-ietf-cose-key-thumbprint-03.html#RFC8747>]”
to “the IANA "CWT Confirmation Methods" registry created by [RFC8747
<https://www.ietf.org/archive/id/draft-ietf-cose-key-thumbprint-03.html#RFC8747>]”.

Section 6 (Example): In the text below, the two clauses both say that
values are correctly ordered, but the orders are different!  Please
correct this to use the same correct order in both.

The required order based on Section 4.2.1 of [RFC8949
<https://www.ietf.org/archive/id/draft-ietf-cose-key-thumbprint-03.html#RFC8949>]
 is:

·"y" (label: -3, data type: bstr)

·"x" (label: -2, data type: bstr)

·"crv" (label: -1, data type: int)

·"kty" (label: 1, data type: int)

The resulting COSE Key structure, in CBOR diagnostic format with
line-breaks added for better readability, with the minimum parameters
in the correct order are.

{
   1:2,
  -1:1,
  -2:h'65eda5a12577c2bae829437fe338701a
       10aaa375e1bb5b5de108de439c08551d',
  -3:h'1e52ed75701163f7f9e40ddf9f341b3d
       c9ba860af7e0ca7ca7e9eecd0084d19c'
}

Section 8 (IANA Considerations):  Add “IANA” before “"CWT Confirmation
Methods" registry”.

Section 9 (Acknowledgements):  Please change “Mike Jones” to “Michael
B. Jones”.  (I use that professionally because there are a whole lot
of Mike Joneses out there!)

Thanks for writing this specification.

-- Mike
