The feature requirement predicates may be used in meta encodings to warn about unsupported features.

Note that with PDDL, the initial state might not assign values to all variables. Instead, unassigned values have to be assigned `false` manually.

Axiom rules are similar to [actions](#actions) in that they modify variables if certain preconditions are satisfied.
Axiom rules are similar to [actions](#actions) in that they modify [variables](#variables) if certain preconditions are satisfied.
However, axiom rules must be applied *immediately* as soon as their preconditions are satisfied.
