Completely understood.  I'm just saying a client may not want results
that aren't ordered over the entire result set.  It might be preferred
to get no results (and have to further refine the search) than to get
truncated results that aren't "globaly" ordered.

I don't feel that strongly about this, just a nice-to-have for some
clients.

This I think is a bigger deal.  If you acknowledge that some servers
cannot (at least easily) order a global result set and then limit the
results returned, then how can this be a MUST?  Seems like the same
issue to me.
