You'll excuse me if I find this less than simple..... you're basically 
writing a vtable in XML.... and a poorly typed one as you're 
overloading methods.

Except, of course, the *name*, which surely shows it's intent... and 
while the effort in reductionism is fine (hey, I did it with 3 methods 
and I bet I could do it with one...), as I've said, generality does 
not equal general applicability and HTTP != REST. 

I've heard Mike ask if this is all necessary for building scalable 
systems, and the answer is obviously "no". Many of the larger systems 
on the planet, such as ATM networks, SABRE, or largish EDI 
infrastructures were built before all this, and do quite well.

In *your* history books anyway.... but I remember a WWW before images 
and before CGI scripts.
