xml-dev - re: XML Documents Are Objects! (or "Killing OO Softly With XML")

[Bill la Forge <b.laforge@opengroup.org>]

Paul,

I've been proposing effectively the same thing on the 
java-xml-interest@opengroup.org list. 

I've been using the term COIN to express this concept--a coin has
two faces, an XML element and a Java Object. 

Bill
