<P>
Entity nodes hold the reference data for an XML Entity -- either
 parsed or unparsed. The nodeName (inherited from Node) will contain
 the name (if any) of the Entity. Its data will be contained in the
 Entity's children, in exactly the structure which an
 EntityReference to this name will present within the document's
 body.
 <P>
 Note that this object models the actual entity, _not_ the entity
 declaration or the entity reference.

 An XML processor may choose to completely expand entities befo
