I agree. I'm doing some investigation into various presentation technologies, 
and have concluded that the best way to architect a web interface is as an 
Model-View-Controller architecture, with the view implemented using XSLT.
It gives the strongest separation between the developer and page builder 
roles. (Of course if the same people are fulfilling both roles, then the 
distinction does become somewhat blurred).

Martin Fowler is producing an extremely interesting and useful summary of 
architectural patterns here: http://www.martinfowler.com/isa/

Transform View is particularly relevant:

To address Simon's wider point, I'm not certain whether the core issue is 
that OO and XML are necessarily poles apart, I think it's more that few 
people have experience in building the types of loosely coupled systems 
that XML facilitates.

Cheers,
