For what it's worth, I would be _very_ much in favor of having a way for 
markup to specify "render this <object> only if the Content-Type matches 
this type" (e.g. a boolean "forceStrictTypeMatch" attribute or whatever).

I don't think we could get away with making this the default behavior, 
but I do think it should be possible.

I don't think we should make it possible for the site embedding the 
<object> to completely override how the server wants it handled, though 
(even the limited amount of overriding we have now makes me pretty unhappy).
