The later.  For instance, here's a 3-level cert hierarchy (with a self-signed
root):

    Serial:   1
    Issuer:   Root CA
    Subject:  Root CA
    
    Serial:   2
    Issuer:   Root CA
    Subject:  UnderRoot CA
    AuthorityCertIssuer:  Root CA
    AuthorityCertSerial:  1

    Serial:   3
    Issuer:   UnderRoot CA
    Subject:  EndEntity
    AuthorityCertIssuer:  Root CA
    AuthorityCertSerial:  2
