/**
*
*
* The XPathNamespace interface is returned by
* XPathResult 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 DOMException with the code
* NO_MODIFICATION_ALLOWED_ERR.
* The core specification describes attributes of the Node
* interface that are different for different node node types but does not
* describe XPATH_NAMESPACE_NODE, so here is a description of
* those attributes for this node type. All attributes of Node
* 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.
*
prefix is the prefix of the namespace represented by the
* node.
*
nodeName is the same as prefix.
*
nodeType is equal to XPATH_NAMESPACE_NODE.
*
namespaceURI is the namespace URI of the namespace
* represented by the node.
*
adoptNode, cloneNode, and
* importNode fail on this node type by raising a
* DOMException with the code NOT_SUPPORTED_ERR.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.
*
See also the Document Object Model (DOM) Level 3 XPath Specification.
*
* This implementation wraps the DOM attribute node that contained the
* namespace declaration.
