-/**
- * 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:
- * <table border='1' cellpadding='3'>
- * <tr>
