Steve,
I have no preference whether in the phrase "CertificateList (e.g., CRL)" the "e.g.," stays or goes. Note that some people use CRL to refer to every instance of a CertificateList, whereas others use CRL, ARL, ACRL, ICRL, DCRL, etc. to distinguish lists used for different purposes. Thus CRL may be either an example of, or a synonym for, CertificateList.
I agree that the state of the cRLSign bit is not relevant to OCSP responses and that CertificateList is the only data structure which requires this bit.
