A representation of the XML 
Manifest element as defined in
 the 
 W3C Recommendation for XML-Signature Syntax and Processing.
 The XML Schema Definition is defined as:
 
 <element name="Manifest" type="ds:ManifestType"/>
   <complexType name="ManifestType">
     <sequence>
       <element ref="ds:Reference" maxOccurs="unbounded"/>
     </sequence>
     <attribute name="Id" type="ID" use="optional"/>
   </complexType>
 
 A 
Manifest instance may be created by invoking
 one of the 
newManifest
 methods of the 
XMLSignatureFactory class; for example:
 
   XMLSignatureFactory factory = XMLSignatureFactory.getInstance("DOM");
   Reference ref = factory.newReference("#reference-1", DigestMethod.SHA1);
   List<Reference> references = Collections.singletonList(ref);
   Manifest manifest = factory.newManifest(references, "manifest-1");
