<P>
Predicate is a expression that evaluates to true or false.
All boolean expressions are implemented as Predicate.
A predicate can have zero or more predicate arguments.
Default predicate operator is AND (conjunction).
Two constant predicates are Predicate.TRUE and Predicate.FALSE.
AND predicate with no argument evaluates to TRUE.
OR predicate with no argument evaluates to FALSE.
Negation of a Predicate creates a new Predicate.
