      <div dir="ltr">Certainly not trying to fight :) I'm assuming I'm
        missing something, so just trying to make sure I understand the
        concerns to see how best to address them.
        <div><br>
        </div>
        <div>How I'm thinking a CA "would" do this, in a way that makes
          it clear to relying parties, is that 1.4.1 / 1.4.2 would
          dictate the acceptable/unacceptable uses, 4.9.1.1 would (in
          order to maintain consistency with the BRs) specifically
          enumerate each and every one of the items in the BRs,
          verbatim.</div>
        <div><br>
        </div>
        <div>Then, a CA could add additional reasons for revocation
          (e.g. 4.9.1.1 (16) "The owner of the CA wakes up on the wrong
          side of the bed that morning"), while the method that the BRs
          require that they MUST have - that is, 4.9.1.1 (4), would
          consistently refer to the definitions in 1.4.1 / 1.4.2 for all
          CAs.</div>
        <div><br>
        </div>
        <div>I think we're actually in quite good agreement that CAs
          should be able to dictate why they revoke, along with
          expecting subscribers be prepared for that, but similarly, we
          want to make sure that CAs enumerate all 14 methods listed in
          the BRs 4.9.1.1, and to be able to do that for 4.9.1.1 (4), we
          need to define what that means consistently :)</div>

                  <p><font face="Calibri">Well, §4.9 of the CPS is about
                      certificate revocation, and here we are discussing

                      revoke a "misused" certificate, whatever "misused"
                      means (to a particular CA). So it seems to me that
                      §4.9 - and particularly §4.9.1 (circumstances for
                      revocation) - can be a suitable location in the
                      CPS where to define "misuse". But I appreciate
