rfc2510bis (CMP) question

[Ari Kermaier <arik@xxxxxxxxx>]

draft-ietf-pkix-rfc2510bis-02 section 3.3.4 has the following syntax for a 
certification response:

  CertResponse ::= SEQUENCE {
      certReqId           INTEGER,
      -- to match this response with corresponding request (a value
      -- of -1 is to be used if certReqId is not specified in the
      -- corresponding request)
      status              PKIStatusInfo,
      certifiedKeyPair    CertifiedKeyPair    OPTIONAL,
      rspInfo             OCTET STRING        OPTIONAL
      -- analogous to the id-regInfo-utf8Pairs OCTET STRING defined
      -- for regInfo in CertReqMsg [rfc2511bis]
  }

I don't understand the comment for the rspInfo field -- rfc2511bis has the 
UTF8Pairs registration info value defined as UTF8String, not OCTET STRING. 
Can anyone enlighten me as to how rspInfo is supposed to be encoded?

Thanks,
