From a performance point of view, one can imagine a factory object that
given xml queries, generates optimal code for executing them. That clearly
could be a lot more efficient than DOM in many many cases.

DOM is already somewhat slow/heavyweight for certain purposes.   While I'm 
sure a lot of good work will be done on query implementation and 
optimization, it's not immediately clear that a query-based implementation 
would in practice be more rather than less efficient compared to DOM.  Not 
that it's a bad idea in principle, but performance is a significant 
barrier to adoption of XML for purposes such as SOAP, and we do need to 
pay more attention to performance as APIs evolve, IMO.  Thanks
