     * the names in the IDP matches one of the names in the DP. If the
     * distribution point name is present in the IDP CRL extension and the
     * distribution field is omitted from the DP, then verify that one of the
     * names in the IDP matches one of the names in the cRLIssuer field of the
     * DP.
     * </p>
     * <p/>
     * (ii) If the onlyContainsUserCerts boolean is asserted in the IDP CRL
     * extension, verify that the certificate does not include the basic
     * constraints extension with the cA boolean asserted.
     * </p>
     * <p/>
     * (iii) If the onlyContainsCACerts boolean is asserted in the IDP CRL
