3.1.6.7.6.4 Note on mSMQSignCertificates and mSMQDigests
The mSMQDigests attribute holds a list of MD5 digests that correspond to the Digest fields of the MQUSERSIGNCERT ([MS-MQMQ] section 2.2.22) structures within the MQUSERSIGNCERTS ([MS-MQMQ] section 2.2.21) structure found in the mSMQSignCertificates attribute. The digests in mSMQDigests MUST be in the same order as the certificates in mSMQSignCertificates. Therefore, when modifying one of these attributes, the other MUST be modified at the same time. This algorithm does not enforce that requirement; it is up to implementers of this algorithm to ensure that it is met.
