surely

mime-type="image/gif"

I hope no-one would ever do this :-}

where is the second place it is maintained? I would put in my archival 
XML file the location of the archival version of the image:

<foo img="testimg.1" mime="application/postscript"/>

I do not need to record any more information anywhere, do I? this
would let my processing application do something sensible always?

I do stress that I am not *advocating* all this for real. But if
notations vanished tomorrow, the world would not come to an end, any
more than it has because inclusions and exclusions sank beneath the waves.
