The "Special Values" in the assistant tab always show all options regardless of compatibility.

Suggestion
Remove options incompatible with the active service property.
(Note: I also noticed a small bug, *ONEBLANK seems to say "User" instead of "Use")

For the WhereClause property of DB services, *EXISTS and *NOTEXISTS don't do anything.
For the RightClause property of BinaryDecision service, NULL doesn't mean anything.

This came up when talking about the binary decision documentation explaining the special values. We wanted to get these fixed for our screenshots in documentation if possible
