yeah, but it's not "equiv" to anything that's in HTTP[1]

The same, by the way, for "Refresh". There again, it purports to be
"equiv" to something that doesn't really exist in HTTP. And again, IE
doesn't really support it when it's presented as a real HTTP header.
(At least, that's how it behaved when I tried it, a while back - and
when MSIE has dug itself into a "feature", it tends to reproduce it in
later versions too, IME).

[1] The HTTP protocol doesn't actually *rule out* additional headers,
so there's nothing that prevents a body from inventing one if they so
choose.
