Overview

The object formula is NOT a subset of subject. True iff log:includes is false. The converse of log:includes. (Understood natively by cwm. The subject formula may contain variables.)

(In cwm, variables must of course end up getting bound before the log:include test can be done, or an infinite result set would result)
