In my ordinary OO design, I have orders, products, etc.
Why aren't those perfectly good Web resources with representations
responding to GET?

(Yeah, I know, POST is another ball of mud...but refinement of
POST while adhering to REST would be a good Web service project...)

What is the essential difference between an XML serialization
and a representation?

I think to resolve the debates over the last year requires
social and political services, not Web services.  If I could get
my wife to understand and be interested in the situation,
she could whip y'all into shape.
