/**
     * If the complete CRL includes an issuing distribution point (IDP) CRL
     * extension check the following:
     * <p/>
     * (i) If the distribution point name is present in the IDP CRL extension
     * and the distribution field is present in the DP, then verify that one of
     * 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
     * extension, verify that the certificate includes the basic constraints
     * extension with the cA boolean asserted.
     * </p>
     * <p/>
     * (iv) Verify that the onlyContainsAttributeCerts boolean is not asserted.
     * </p>
     *
     * @param dp   The distribution point.
     * @param cert The certificate.
     * @param crl  The CRL.
