RE: EDITS for Section 10.16 (Content-Location)

It is inappropriate to say that I can't use the content-location URI --
in my internal corporate Web, the spoofing problem may not be an issue,
and caching efficiency might be served by using the Content-Location

There does need to be a comment in the security considerations section
about spoofing and Content-Location, but I think there already is one.
