E.g. a reference in frame/@src is meant to be onLoad, but some user 
agents will create an onRequest reference.

That's the problem with the "identified by a single URI". Different 
results of POST forms are another thing that cannot be "identified by a 
single URI".

So the web page identifer in some cases cannot be just a URI, but must 
be able to include the necessary parameters (in HTTP: headers, message 
body) that the resulting response is based upon.
