public class ElementOverNodeInfo extends NodeOverNodeInfo implements Element
The class provides read-only access to the tree; methods that request updates all fail with an UnsupportedOperationException.
Note that contrary to the DOM specification, this implementation does not expose namespace declarations as attributes.
