case sensitive vs insensitive

On the working group call today we were discussing whether SQL identifiers
in R2RML should be interpreted in a case insensitive or case sensitive
manner. I think I mis-heard Ted's proposal at the end.

Ted - If you were saying that for the simplest case they need to be
interpreted in a case _in_sensitive manner... then "yes" I agree.

I realized after the call that I may have been arguing for the same thing
you were saying... if so, sorry for the confusion.
