I've pointed out that simply talking about objects and methods is
insufficient to actually use the object properly.  What's wrong with your
point is that you miss Data.  The REST thesis explicitly calls out data in
his description of architectural elements, and very astutely says, "The
nature of the data elements within a network-based application architecture
will often determine whether or not a given architectural style is
appropriate. ".

I'm pointing out that the nature of data in web services is XML, and that
has impacts on the appropriate architectural style.

The more I read Roy's thesis and speak with him, the more I'm impressed.
Architectures are all about the requirements and optimizations one wants to
meet.  And one architecture doesn't fit all sizes.
