It might be good to remind that the 10 comes from the cose algorithm number specified in item 0 of the suite.

K_2e = HKDF-Expand( PRK, info, length) should that not be: K_2e = HKDF-Expand( PRK_3e2m, info, length) .
If not, what should it be?
The number of bytes are sometimes a bit magical; In some cases it can be reminded that ECDH uses 32 bytes and the signature of the ed25519 is 32 bytes as well.
page 51: may be mention that for MAC_2, 8 bytes is length of TAG
