More separation

[Tony Linde]

That's right Roy, so:
  http://blahblah.org/cgi-bin/cone?Catalog=Hedgehog
would be one service accessing multiple datasets and
  http://wibblewibble.org/cgi-bin/cone?Catalog=Messier
would be a second service accessing the one dataset.

That separation is what we need to mirror in the schema.

Cheers,
Tony.
