 *
 *
 * The X509Data  Element (http://www.w3.org/TR/xmldsig-core/#sec-X509Data)
 *
 * An X509Data element within KeyInfo contains one or more identifiers of keys 
 * or X509 certificates (or certificates' identifiers or a revocation list). 
 * The content of X509Data is:
 *
 *  1. At least one element, from the following set of element types; any of these may appear together or more than once iff (if and only if) each instance describes or is related to the same certificate:
 *  2.
 *    * The X509IssuerSerial element, which contains an X.509 issuer 
 *	distinguished name/serial number pair that SHOULD be compliant 
 *	with RFC2253 [LDAP-DN],
 *    * The X509SubjectName element, which contains an X.509 subject 
 *	distinguished name that SHOULD be compliant with RFC2253 [LDAP-DN],
 *    * The X509SKI element, which contains the base64 encoded plain (i.e. 
 *	non-DER-encoded) value of a X509 V.3 SubjectKeyIdentifier extension.
 *    * The X509Certificate element, which contains a base64-encoded [X509v3] 
 *	certificate, and
 *    * Elements from an external namespace which accompanies/complements any 
 *	of the elements above.
 *    * The X509CRL element, which contains a base64-encoded certificate 
 *	revocation list (CRL) [X509v3].
 *
 * Any X509IssuerSerial, X509SKI, and X509SubjectName elements that appear 
 * MUST refer to the certificate or certificates containing the validation key.
 * All such elements that refer to a particular individual certificate MUST be 
 * grouped inside a single X509Data element and if the certificate to which 
 * they refer appears, it MUST also be in that X509Data element.
 *
 * Any X509IssuerSerial, X509SKI, and X509SubjectName elements that relate to 
 * the same key but different certificates MUST be grouped within a single 
 * KeyInfo but MAY occur in multiple X509Data elements.
 *
 * All certificates appearing in an X509Data element MUST relate to the 
 * validation key by either containing it or being part of a certification 
 * chain that terminates in a certificate containing the validation key.
 *
 * No ordering is implied by the above constraints.
 *
 * Note, there is no direct provision for a PKCS#7 encoded "bag" of 
 * certificates or CRLs. However, a set of certificates and CRLs can occur 
 * within an X509Data element and multiple X509Data elements can occur in a 
 * KeyInfo. Whenever multiple certificates occur in an X509Data element, at 
 * least one such certificate must contain the public key which verifies the 
 * signature.
