| /** |
| * The <code>DOMAttr</code> class refers to an attribute of an XML element. |
| * |
| * Typically the allowable values for the |
| * attribute are defined in a documenttype definition. |
| * <p><code>DOMAttr</code> objects inherit the <code>DOMNode</code> interface, but |
| * since attributes are not actually child nodes of the elements they are associated with, the |
| * DOM does not consider them part of the document tree. Thus, the |
| * <code>DOMNode</code> attributes <code>parentNode</code>, |
| * <code>previousSibling</code>, and <code>nextSibling</code> have a null |
| * value for <code>DOMAttr</code> objects. The DOM takes the view that |
| * attributes are properties of elements rather than having a separate |
| * identity from the elements they are associated with; this should make it |
| * more efficient to implement such features as default attributes associated |
| * with all elements of a given type. Furthermore, attribute nodes |
| * may not be immediate children of a <code>DOMDocumentFragment</code>. However, |
| * they can be associated with <code>DOMElement</code> nodes contained within a |
| * <code>DOMDocumentFragment</code>. In short, users of the DOM |
| * need to be aware that <code>DOMAttr</code> nodes have some things in common |
| * with other objects inheriting the <code>DOMNode</code> interface, but they |
| * also are quite distinct. |
