I believe the working group should focus on finding areas that are in the BRs, don't exist in the CSBRs but are considered meaningful for code signing certificates and update the CSBRs. This will avoid any ambiguities about the expectations and keep CAs and auditors focused on one document with direct references to TLS BRs and EV Guidelines.<br><br>For example, in 17.5 of the CSBRs, we have clear requirements for EV Code Signing Certificates. Does this mean that 8.7 of the BRs applies and this requirement is also applicable for the non-EV Code Signing Certificates? One is explicitly called out and the other is implicit according to this interpretation.<br><br>Similarly for the <a href="https://github.com/cabforum/servercert/blob/main/docs/BR.md#722-crl-and-crl-entry-extensions">CRL profile</a> and many other cases. These were recent changes to the TLS BRs.
