Layered Programming

Hi all,

I've put up a new article on the website called Layered Programming.
It looks at some of the problems facing software developers today,  
and how a clean separation of information layers using XML Namespaces  
could be part of the solution.

The article is still a draft, feedback is, as always, very welcome!
