For example, 21: * <code>Text</code> nodes may not have children, and adding children to 22: * such nodes results in a <code>DOMException</code> being raised. 23: * <p>The attributes <code>nodeName</code>, <code>nodeValue</code> and 24: * <code>attributes</code> are included as a mechanism to get at node 25: * information without casting down to the specific derived interface. In 26: * cases where there is no obvious mapping of these attributes for a 27: * specific <code>nodeType</code> (e.g., <code>nodeValue</code> for an 28: * <code>Element</code> or <code>attributes</code> for a <code>Comment</code> 29: * ), this returns <code>null</code>.
