Public Key Value of XMSS, XMSSMT, and HSS-LMS

[xipki]

As specified in https://datatracker.ietf.org/doc/html/draft-ietf-lamps-x509-shbs-00:

pk-XMSS-HashSig PUBLIC-KEY ::= {
   IDENTIFIER id-alg-xmss-hashsig
   KEY XMSS-HashSig-PublicKey
   PARAMS ARE absent
   CERT-KEY-USAGE
      { digitalSignature, nonRepudiation, keyCertSign, cRLSign } }

XMSS-HashSig-PublicKey ::= OCTET STRING

And here the definition of SubjectPublicKeyInfo in RFC 5280

   SubjectPublicKeyInfo  ::=  SEQUENCE  {
        algorithm            AlgorithmIdentifier,
        subjectPublicKey     BIT STRING  }

Shall the XMSS public key be an OCTET-STRING(public key bytes), or just the "public key bytes"?

This applies also to the XMSS-MT, HSS-LMS.
