I think such a design could be quite a bit simpler than DOM since it could:

1. Be read-only
2. Only support what's necessary for the XPath data model

This would be a lot easier for other object models than implementing 
full DOM. Whole classes would be cut out: DocType, CDATASection, Entity, 
EntityReference, etc.; and we could probably eliminate more than half of 
the methods in the classes that remained. Not only would all the mutator 
methods disappear. We could get rid of all the non-namespace aware 
methods. Finally, since this would be intended for machine use rather 
than for direct programming, we could eliminate a lot of convenience 
methods as well.
