I have finished the writing about the subject. The URI is 
http://dfdf.inesc-id.pt/tr/web-arch.

In short, I think the current AWWW document should be modified to 
emphasize the following two points:

(1) The abstract nature of "resource" with regard to the web.
(2) The role of URI as an interface, in addition to a name, for the web
 
I think the failure to recognize the above two points are the reasons 
for the faulty impression of URI's ambiguity and debate about 
"information resource".  As for the latter, I think httpRange-14 
answered a wrong question because 200 should indicate an informational 
*URI* but not an information *resource*.
