* Elements represent most of the "markup" and structure of the document. They

*
* 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
