/**
* 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:

/**
* Tests whether two nodes are equal.
* <br>This method tests for equality of nodes, not sameness (i.e.,
* whether the two nodes are references to the same object) which can be
* tested with <code>Node.isSameNode()</code>. All nodes that are the
* same will also be equal, though the reverse may not be true.
* <br>Two nodes are equal if and only if the following conditions are
* satisfied:
* <ul>
* <li>The two nodes are of the same type.
* </li>
* <li>The following string
* attributes are equal: <code>nodeName</code>, <code>localName</code>,
* <code>namespaceURI</code>, <code>prefix</code>, <code>nodeValue</code>
* . This is: they are both <code>null</code>, or they have the same
* length and are character for character identical.
* </li>
* <li>The
* <code>attributes</code> <code>NamedNodeMaps</code> are equal. This
* is: they are both <code>null</code>, or they have the same length and
* for each node that exists in one map there is a node that exists in
* the other map and is equal, although not necessarily at the same
* index.
* </li>
* <li>The <code>childNodes</code> <code>NodeLists</code> are equal.
* This is: they are both <code>null</code>, or they have the same
* length and contain equal nodes at the same index. Note that
* normalization can affect equality; to avoid this, nodes should be
* normalized before being compared.
* </li>
* </ul>
* <br>For two <code>DocumentType</code> nodes to be equal, the following
* conditions must also be satisfied:
* <ul>
* <li>The following string attributes
* are equal: <code>publicId</code>, <code>systemId</code>,
* <code>internalSubset</code>.
* </li>
* <li>The <code>entities</code>
* <code>NamedNodeMaps</code> are equal.
* </li>
* <li>The <code>notations</code>
* <code>NamedNodeMaps</code> are equal.
* </li>
* </ul>
* <br>On the other hand, the following do not affect equality: the
* <code>ownerDocument</code>, <code>baseURI</code>, and
* <code>parentNode</code> attributes, the <code>specified</code>
* attribute for <code>Attr</code> nodes, the <code>schemaTypeInfo</code>
* attribute for <code>Attr</code> and <code>Element</code> nodes, the
* <code>Text.isElementContentWhitespace</code> attribute for
* <code>Text</code> nodes, as well as any user data or event listeners
* registered on the nodes.
* <p ><b>Note:</b> As a general rule, anything not mentioned in the
