I hope I'm not mis-representing Paul here, but as I've always read him (and 
agreed), his point is that XML, and the various ancillary technologies such as 
DOM and XML Schema, are more appropriate for content-exchange than for core 
business-object modeling.

I don't think it makes sense to build a business-object model on top of DOM, 
but I do think it makes sense to define an exchange protocol that selializes 
objects to XML representations using DOM as a programmatic interface.  
Hopefully in this effort, one can leverage the support of such technologies as 
WDDX and XML-RPC, especially as they develop closer ties with other object 
technologies, including the locally much-maligned CORBA.

I think it also makes sense to use the DOM to develop a user-interface layer 
for such objects, possibly using the same WDDX or XML-RPC mappings in 
association with a set of style-sheets (although this is just one of many 
possible mechanisms).
