Well, the thread is on XML-aware programming languages, and every such 
thing needs to define a data model.

No language designer can seriously claim that his language is the right 
one for all circumstances.

But, to process XML in a program, you can never do without the tree view.

Aha, event-based and in which order are the events called?

But tools bring you only this far, and a programming language is 
providing more coherence than using a set of ill-matching tools. At 
least that is the assumption under which to design an XML aware 
programming language, and I find it valid.
