xml-dev - help me understand DOM XML Level 1

[Siping Liu <siping.liu@gte.com>]

Hi,

I'm trying to implement the DOM interface on the listener side of the
SAX interface. The
DOM Core Level 1 interface looks clear enough to me. But I get confused
by the
definition in DOM XML Level 1, especially "XMLNode" -- why isn't it
derived from
"Note"? Can I traverse a tree with this interface and how? Why does it
have
this "getEntityReference()"  method, I don't see the concept of having
an "entity reference"
attached to each node (such as an element) in XML spec.

Thanks for your help.
