+	/// Elements may have attributes associated with them; since the Element interface
+	/// inherits from Node, the generic Node interface attribute attributes may
+	/// be used to retrieve the set of all attributes for an element. There are
+	/// methods on the Element interface to retrieve either an Attr object by name
+	/// or an attribute value by name. In XML, where an attribute value may contain
+	/// entity references, an Attr object should be retrieved to examine the possibly
+	/// fairly complex sub-tree representing the attribute value.
