I think it's important to keep this description.  Many attributes
inherited from Node have different meanings for different subclasses. 
Notations can be added to the effect that they are subclasses.  I think
rather that the other inherited attributes, especially nodeName and
nodeValue, should be described in every derived class.

Note that the DOM spec describes namespaceURI for attributes.  I think
the DOM spec is a good model of where to do this, and where not to
bother.
