RE: [whatwg] Creative Commons Rights Expression Language

If metadata are useless, it is fine not to use them.  However, they should
never go into content; the browser could display them as document properties
on demand instead in order that humans could keep them up to date.  The
reason is that having metadata in content results in circular dependency:
content is licensed by a license that is contained in the content, in
particular the license statement itself is licensed by the same license.
This is illogical.
