/**
 * A representation of the XML <code>X509IssuerSerial</code> element as 
 * defined in the <a href="http://www.w3.org/TR/xmldsig-core/">
 * W3C Recommendation for XML-Signature Syntax and Processing</a>. 
 * An <code>X509IssuerSerial</code> object contains an X.509 issuer 
 * distinguished name (DN) and serial number pair. The XML schema definition is 
 * defined as: 
 *
 * <pre>
 *   &lt;element name="X509IssuerSerial" type="ds:X509IssuerSerialType"/&gt;
 *   &lt;complexType name="X509IssuerSerialType"&gt;
 *     &lt;sequence&gt;
 *       &lt;element name="X509IssuerName" type="string"/&gt; 
 *       &lt;element name="X509SerialNumber" type="integer"/&gt; 
 *     &lt;/sequence&gt;  
 *   &lt;/complexType&gt;
 * </pre>
 *
 * An <code>X509IssuerSerial</code> instance may be created by invoking the
 * {@link KeyInfoFactory#newX509IssuerSerial newX509IssuerSerial} method 
 * of the {@link KeyInfoFactory} class, and passing it a 
 * <code>String</code> and <code>BigInteger</code> representing the X.500
 * DN and serial number. Here is an example of creating an 
 * <code>X509IssuerSerial</code> from the issuer DN and serial number of an 
 * existing {@link X509Certificate}:
 * <pre>
 * KeyInfoFactory factory = KeyInfoFactory.getInstance("DOM");
 * X509IssuerSerial issuer = factory.newX509IssuerSerial
 *     (cert.getIssuerX500Principal().getName(), cert.getSerialNumber());
 * </pre>
