There is a world of difference between *a* data model for XML and 
*the* data model for XML. There are many data models for XML, none of 
which can plausibly claim to be *the* data model for XML.

XML data models include the XPath 1.0 model, the XPath 2.0 + XQuery 
model, the Infoset, the PSVI, the DOM data model, the JDOM data 
model, and many more all of which are related but have subtle and 
important differences. There are also things like the SAX model or 
the models exposed by different data binding APIs that really don't 
look much like these at all.
