A complete lattice with a partially ordered set, join operator (LUB), meet operator (GLB), top element, and bottom element (e.g. for abstract domains).
Checks whether the current abstract value is an actual value of the complete lattice
(this may include the Top or Bottom element if they are also values and no separate symbols, for example).
