<p>Notwithstanding an author's declaration of their intention to use specific content or processor profiles, a <loc href="#terms-processor">processor</loc>
is allowed to override the author's declaration of either (or both) content or (and) processor profiles. This is expected to be typical behavior

the <loc href="#terms-processor">processor</loc> is not able to dereference (download) and process a
