Ho, hum.

I disagree. You can either parse the query at the client side, which is
flawed, imo, or you can make the backend send the information along with
the rest of the Field metadata. Yes, I know that would be a major change,
that would break all existing interfaces. Yes, I know it would be a pain
in the latter regions to fix. One thing you might want to consider,
though, is that the information is necessary for the
UpdateableResultSets. How, else, are you going to execute the updates?
