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.
