Comments inline.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>> As I assume that the CAs use the Enterprise RA to perform the same function, can we consolidate the definition and only include the definition in the BRs?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>As you note, the EVG definition isn’t used anywhere, so it can be safely removed. Along with that removal, we should consider addressing some issues with Section 14.2.2. This section speaks to a “Enterprise EV Certificate” that must be issued to the Enterprise RA that lists the (Base) Domain Names for which that RA may issue EV Certificates for. There are a few problems with this section:<o:p></o:p></p><ol style='margin-top:0in' start=1 type=1><li class=MsoListParagraph style='margin-left:0in;mso-list:l0 level1 lfo3'>The language doesn’t explicitly require a demonstration of control of the Domain Namespace for the included domains in the Enterprise EV Certificate; a blanket permission to issue for “third and higher domain levels” is seemingly granted. Prior to the introduction of method 20, I believe all domain validation methods allowed for the reuse of validation data to validate subdomains of the Authorization Domain Name (ADN), so this was not an issue. However, since there are now several validation methods that prohibit “FQDN != ADN” validation, this appears to be a loophole.<o:p></o:p></li><li class=MsoListParagraph style='margin-left:0in;mso-list:l0 level1 lfo3'>14.2.2 (5) seemingly has a provision to allow signing Enterprise EV Certificates using Root CA Private Keys, contradicting Section 12’s prohibition on using Root CA Private Keys for signing EV Certificates.<o:p></o:p></li></ol><p class=MsoListParagraph><o:p> </o:p></p><p class=MsoNormal>> EVG 13 states “CAs MUST ensure that CRLs for an EV Certificate chain can be downloaded in no more than three (3) seconds over an analog telephone line under normal network conditions.”<o:p></o:p></p><ul style='margin-top:0in' type=disc><li class=MsoListParagraph style='margin-left:0in;mso-list:l5 level1 lfo6'>This requirement was in draft 11 in 2007. I believe that it was added to support dial up Windows users.<o:p></o:p></li><li class=MsoListParagraph style='margin-left:0in;mso-list:l5 level1 lfo6'>Is it possible that we could drop this requirement and only require BR 4.9?<o:p></o:p></li></ul><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>In addition to removing this antiquated language, we should also consider removing 9.7 (4), which states:<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>“The cRLDistributionPoints extension MUST be present in Subscriber<o:p></o:p></p><p class=MsoNormal>Certificates if the certificate does not specify OCSP responder locations in an<o:p></o:p></p><p class=MsoNormal>authorityInformationAccess extension”<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>SC 31 removed the “OCSP stapling” exception to permit CAs to omit the AIA OCSP pointer. As a result, EV certificates MUST contain an OCSP AIA pointer in all cases.
