<P>
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:
