made it perfectly clear that what you were looking for was a COMPLETE
list of OFFICIAL meta tags. Then, when I tell you there is NO SUCH
THING,
I have a vague recollection that there _is_ such a thing (or at least
the claim of such) as part of the standards for UK government sites
and their eGMS standards (wheels reinvented here). You can imagine
just how bad an idea this was, how pointless, how unworkable, and
given that this eGMS crap is cooked up from some unholy combination of
Andy Mabbett and Prince2, just how badly it's implemented.
