I see this as EXACTLY equivalent to putting RPC "style" information 
into the interface; all we're doing here is putting Web "style" 
information into the interface.

In the same way that some tools can use RPC "style" information to make 
modelling choices, so too might I want to use Web/RESTful hints to help 
the abstract modelling of my application; this is very useful at the 
interface level.

Put another way, if this information is relegated to the binding only, 
WSDL is restricted to only modelling interchanges as "in/out" 
abstractions, rather than richer concepts like state transfer, etc.

If I were Director for a day, I'd have a very hard time Recommending 
something that purported to be a "Web" description language, when it 
accommodates abstract modelling of RPC, yet fails to do so for REST.


P.S. This requirement could be satisfied by defining a few new 
"RESTful" style attribute URIs; e.g., 
style="http://www.w3.org/.../GET". However, that's syntactically ugly 
and unnecessary, which brings us back to issue 217. Not that I want to 
beat a dead horse or anything.
