What you propose should be solved using the URI: header.  URI: can tell
you the URL for *exactly* what you have now or it can tell which attributes
can be varied.  That's all it should need to know and that's a *LOT* more
information than coding a content-type in a URL *and* it doesn't break
existing practice.
