| * Elements represent most of the "markup" and structure of the |
| * document. They contain both the data for the element itself |
| * (element name and attributes), and any contained nodes, including |
| * document text (as children). |
| * <P> |
| * Elements may have Attributes associated with them; the API for this is |
| * defined in Node, but the function is implemented here. In general, XML |
| * applications should retrive Attributes as Nodes, since they may contain |
| * entity references and hence be a fairly complex sub-tree. HTML users will |
| * be dealing with simple string values, and convenience methods are provided |
| * to work in terms of Strings. |
