Hrm, that's no good then.  *Something* has to be done about it,
though, because just display:none'ing the fallback content doesn't
allow legacy video clients to be tried, which the spec explicitly
mentions (and just plain makes sense anyway - without it, <video>
adoption will be substantially slower).

We need *some* way to indicate that particular elements aren't to be
activated at all in certain circumstances.

On a side note, does the old <object><embed></> trick work only
because the browsers that support that use of <object> don't support
that use of <embed>, and vice versa?  So even though the <embed> is
parsed in an <object>-supporting browser, it doesn't activate?  If so,
then it seems like our problem is *too much* interop now.  ^_^
