How about something like these?

http://dom4j.org/apidocs/org/dom4j/Node.html
http://dom4j.org/apidocs/org/dom4j/CDATA.html
http://dom4j.org/apidocs/org/dom4j/Attribute.html

A few ideas for methods could be...

* getParent()
* getDocument()
* accept(Visitor)
* return itself as a snippet of XML text.
* return the XPath 'string-value' of the node as per the XPath spec.
* return the XPath expression required to navigate to the node. (e.g.
"foo/bar/@name")
* evaluate XPath expressions relative to the node.

I'm sure there could be others.
