DISCUSS:
----------------------------------------------------------------------

Are the wrong data structures being referenced or did I misunderstand something?

** Section 5.  Per “Abbreviated counter signatures use the structure
COSE_Countersign1”, this doesn’t seem consistent with the more detailed
write-up in Section 5.2 which says that “The byte string representing the
signature value is placed in the CounterSignature0 attribute”.  The document
makes no other reference to COSE_Countersign1.

The shepherd write-up notes that ‘one item to note is the decision to keep the
context string "COSE_Countersign1" for abbreviated countersignatures’. 
However, I found no such reference in Step 1 of Section 4.4 (page 22) which
enumerated the possible strings.

** What is the intended name of the structure for the Counter Signature -- is
it COSE_Countersignature or COSE_Countersign?

-- Table 1, Section 2, Section 4.4 and Section 5.1 (to include the CDDL)
reference COSE_Countersignature

but
-- Section 5. Per “Full counter signatures use the structure COSE_Countersign …”

-- Section 5.1.  Per “A tagged COSE_Countersign structure …”

Thanks for making an easy to read and compare bis document.

** Section 4.4.  Per the the following item in the list, ‘"CounterSignature"
for signatures used as counter signature attributes.’, can this be more
precisely stated as to reference the particular COSE_* data type?  The other
items in this list are more precise in naming the corresponding
structure/attributes.
