I'm not so sure all systems can turn case sensitivity on or off easily.

Some do other things than simply case sensitive or case insensitive by
default.  By default Verity is case sensitive if the query term has
mixed case and insensitive otherwise, but does have a case

Some other full text systems don't necessarily have a case
operator so they wouldn't easily be able to conform to the
standard if there is no out for being only case sensitive or  case

Do we need to include query discovery for control of case
sensitivity capabilities?
