TElCRLDistributionPointsExtension is a descendant of TElCustomExtension class.
The following paragraph is taken from RFC 2459 (Housley, et. al.), part 220.127.116.11:
«The CRL distribution points extension identifies how CRL information is obtained. The extension SHOULD be non-critical, but this profile recommends support for this extension by CAs and applications. Further discussion of CRL management is contained in section 5.
If the cRLDistributionPoints extension contains a DistributionPointName of type URI, the following semantics MUST be assumed: the URI is a pointer to the current CRL for the associated reasons and will be issued by the associated cRLIssuer. If the distributionPoint omits reasons, the CRL MUST include revocations for all reasons. If the distributionPoint omits cRLIssuer, the CRL MUST be issued by the CA that issued the certificate.»
