Nor is it made harder.

Complexity is in the work required to create the artifact.  One 
might also argue that if it is harder to enter the artifact by 
hand or read it with that same eye, and that a graphical UI is 
required to enter it, it is more complex and the advantage of 
the UI is the crutch to support the complexity.

Anyway, without responding to the details of our exchange, you 
miss the point:  Does XML-Data offer more functionality?  If 
so, then good.  If not, then why bother?  I thought it did, 
but I could be wrong.

Good to know.  I guess I should formerly swear my lack of 
initiation in the Hermetic Order of the Golden Dawn as long 
as we forswearing organizations out to conquer Middle Earth. ;-)

On with the show.
