/**
* A representation of the XML Object
element as defined in
* the
* W3C Recommendation for XML-Signature Syntax and Processing.
* An XMLObject
may contain any data and may include optional
* MIME type, ID, and encoding attributes. The XML Schema Definition is
* defined as:
*
*
* <element name="Object" type="ds:ObjectType"/>
* <complexType name="ObjectType" mixed="true">
* <sequence minOccurs="0" maxOccurs="unbounded">
* <any namespace="##any" processContents="lax"/>
* </sequence>
* <attribute name="Id" type="ID" use="optional"/>
* <attribute name="MimeType" type="string" use="optional"/>
* <attribute name="Encoding" type="anyURI" use="optional"/>
* </complexType>
*
*
* A XMLObject
instance may be created by invoking the
* {@link XMLSignatureFactory#newXMLObject newXMLObject} method of the
* {@link XMLSignatureFactory} class; for example:
*
*
* XMLSignatureFactory fac = XMLSignatureFactory.getInstance("DOM");
* List content = Collections.singletonList(fac.newManifest(references)));
* XMLObject object = factory.newXMLObject(content, "object-1", null, null);
*
*
* Note that this class is named XMLObject
rather than
* Object
to avoid naming clashes with the existing
* {@link java.lang.Object java.lang.Object} class.
