/**

|
* document. They contain both the data for the element itself
|

|
|
* 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
|

|
