And even that doesn't really do the trick.

I maintain my web page in CVS, so I use $Date$ keywords as a cheap and
easy way to build 'Last Modified'.  But I modify pages all the time to
fix up spelling and grammar mistakes, or clarify labyrinthine
sentences.  If I didn't make use of templating and cross-includes, I'd
be modifying every page every time I made a change to the site
look&feel or some of the common code.

All of these would be changing the 'Last Modified', whether by
filesystem mtime or the revision $Date$.  But none of them say
anything about whether I checked that the content was up to date.
There's no way an automated system can know whether I checked or
updated something like that, so it can hardly be anything HTML (or
HTTP, or some server-side programming language for that matter) can
address.
