1) Add/revise the following definitions:

Issuance Time: The time at which a Certificate’s digital signature is
calculated.

Short-Lived Certificate: A Certificate with a Validity Period less than 96
hours and a notBefore time no earlier than 24 hours before the Issuance Time
and a notAfter time no later than 72 hours after the Issuance Time.

Validity Period: The period of time measured from notBefore through
notAfter, inclusive. the date when the Certificate is issued until the
Expiry Date.

2) Modify Section 4.9.10 as follows:

4.9.10. On‐line Revocation Checking Requirements

Effective 1 January 2013, the CA SHALL support an OCSP capability using the
GET method for Certificates issued in accordance with these Requirements.

For the status of Subscriber Certificates other than a Short-Lived
Certificate containing a cRLDistributionPoints extension: The CA SHALL
update information provided via an Online Certificate Status Protocol at
least every four days. OCSP responses from this service MUST have a maximum
expiration time of ten days.

3) Modify Section 7.1.2.3 as follows:

7.1.2.3. Subscriber Certificate …

b. cRLDistributionPoints This extension MUST be present for Short-Lived
Certificates that lack an authorityInformationAccess extension and MAY be
present for all other certificates. If present, it MUST NOT be marked
critical, and it MUST contain the HTTP URL of the CA’s CRL service. See
Section 13.2.1 for details.

c. authorityInformationAccess With the exception of stapling and Short-Lived
Certificates, which is noted below, this extension MUST be present. It MUST
NOT be marked critical, and it MUST contain the HTTP URL of the Issuing CA’
s OCSP responder (accessMethod = 1.3.6.1.5.5.7.48.1). It SHOULD also contain
