In Section 9 of RFC 8410, the following ASN.1 type definition is given:

     pk-Ed25519 PUBLIC-KEY ::= {
         IDENTIFIER id-Ed25519
         -- KEY no ASN.1 wrapping --
         PARAMS ARE absent
         CERT-KEY-USAGE {digitalSignature, nonRepudiation,
                         keyCertSign, cRLSign}
         PRIVATE-KEY CurvePrivateKey
     }

Is "PRIVATE-KEY" correct?

I feel like this structure should contain a BIT-STRING that encodes the 
bytes of an Ed25519 public key.

(and, yes, I checked the errata.  there is no mention of this there.)

thanks,
