It would only be needed for the description in RDF, so that only means
around 3 extra mime types. This has to be weighed against reconfiguring the
web.

Yes, as is MGET, except there the switch is shunted even further back into
the machinery. I agree this looks on the surface a more elegant approach,
but if the current web can be used without breaking anything, then I think
that should be the preferred approach. (I don't think anything gets broken
with the mimetype approach, the description can be considered just another
representation of the identified resource).

Ok, so perhaps the mimetype approach isn't the best, but I still hold out
hope for an approach that doesn't need lowish-level rewiring.

I'm certainly clearer about the issues, so thanks for that.

Cheers,
Danny.
