/**

 * The <code>DOMXPathNamespace</code> interface is returned by <code>DOMXPathResult</code>

 * interfaces to represent the XPath namespace node type that DOM lacks. There is no

 * public constructor for this node type. Attempts to place it into a hierarchy or a 

 * NamedNodeMap result in a DOMException with the code HIERARCHY_REQUEST_ERR. This node

 * is read only, so methods or setting of attributes that would mutate the node result 

 * in a <code>DOMException</code> with the code NO_MODIFICATION_ALLOWED_ERR.

 * The core specification describes attributes of the <code>DOMNode</code> interface that 

 * are different for different node types but does not describe XPATH_NAMESPACE_NODE, 

 * so here is a description of those attributes for this node type. All attributes of

 * <code>DOMNode</code> not described in this section have a null or false value.

 * ownerDocument matches the ownerDocument of the ownerElement even if the element is later adopted.

 * nodeName is always the string "#namespace".

 * prefix is the prefix of the namespace represented by the node.

 * localName is the same as prefix.

 * nodeType is equal to XPATH_NAMESPACE_NODE.

 * namespaceURI is the namespace URI of the namespace represented by the node.

 * nodeValue is the same as namespaceURI.

 * adoptNode, cloneNode, and importNode fail on this node type by raising a DOMException with the code NOT_SUPPORTED_ERR.

 * Note: In future versions of the XPath specification, the definition of a namespace node may

 * be changed incomatibly, in which case incompatible changes to field values may be required to

 * implement versions beyond XPath 1.0.
