/**
* The <code>Node</code> interface is the primary datatype for the entire
* Document Object Model. It represents a single node in the document tree.
* While all objects implementing the <code>Node</code> interface expose
* methods for dealing with children, not all objects implementing the
* <code>Node</code> interface may have children. For example,
* <code>Text</code> nodes may not have children, and adding children to
* such nodes results in a <code>DOMException</code> being raised.
* <p>The attributes <code>nodeName</code>, <code>nodeValue</code> and
* <code>attributes</code> are included as a mechanism to get at node
* information without casting down to the specific derived interface. In
* cases where there is no obvious mapping of these attributes for a
* specific <code>nodeType</code> (e.g., <code>nodeValue</code> for an
* <code>Element</code> or <code>attributes</code> for a <code>Comment</code>
* ), this returns <code>null</code>. Note that the specialized interfaces
* may contain additional and more convenient mechanisms to get and set the
* relevant information.
* <p>The values of <code>nodeName</code>,
* <code>nodeValue</code>, and <code>attributes</code> vary according to the
* node type as follows:
