/**
* Represents the CRL Issuing Distribution Point Extension (OID = 2.5.29.28).
*
*
* The issuing distribution point is a critical CRL extension that
* identifies the CRL distribution point and scope for a particular CRL,
* and it indicates whether the CRL covers revocation for end entity
* certificates only, CA certificates only, attribute certificates only,
* or a limited set of reason codes.
*
*
* The extension is defined in Section 5.2.5 of
* Internet X.509 PKI
* Certificate and Certificate Revocation List (CRL) Profile.
*
*
* Its ASN.1 definition is as follows:
*
* id-ce-issuingDistributionPoint OBJECT IDENTIFIER ::= { id-ce 28 }
*
* issuingDistributionPoint ::= SEQUENCE {
* distributionPoint [0] DistributionPointName OPTIONAL,
* onlyContainsUserCerts [1] BOOLEAN DEFAULT FALSE,
* onlyContainsCACerts [2] BOOLEAN DEFAULT FALSE,
* onlySomeReasons [3] ReasonFlags OPTIONAL,
* indirectCRL [4] BOOLEAN DEFAULT FALSE,
* onlyContainsAttributeCerts [5] BOOLEAN DEFAULT FALSE }
