public abstract class ObjectReference

extends XMLElement

Base class for elements that serve as references. I.e., elements consisting of a URI identifying the referenced object, along with any transformation and type information needed to process it.

The base XML schema for such elements is:

        <complexType>
                <sequence>
                        <element ref="Transforms" minOccurs="0"/>
                </sequence>
                <attribute name="URI" type="anyURI" use="optional"/>
        </complexType>
        

The Transforms element is defined in the application's namespace, and is a sequence of dsig:Transform elements.
