<p class="MsoNormal">Thanks for the comment. <o:p></o:p></p>

<p class="MsoNormal">I believe that support for suspension is not appropriate for the publicly-trusted S/MIME for the following reasons:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<ul style="margin-top:0in" type="disc">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">For S/MIME recipients this could be confusing, for example in the case that a signature on an email could be valid or not on different days, with no explanation. The CABF stance for
publicly-trusted certificates has been that once a certificate is "bad" on a CRL it can't be "unbad".<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">For Certificate Issuers, this could also create undesired inconsistency in revocation handling across publicly-trusted certificate types, particularly in light of the changes implemented
recently to create CRL consistency under the Mozilla policy for TLS.<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">For Certificate Consumers, we have no known “default” for how revocation checking is performed in client software, or how the certificateHold revocation code is treated.<o:p></o:p></li></ul>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I recall the WG did review this draft section about a year ago, but as there was no comment (often the case with ‘pick ups’ from other CABF standards) the topic is not specifically acknowledged in the minutes.<o:p></o:p></p>
