Which rules are not mandatory and indicated by the absence of 'shall' or 'shall not'?

Explanation:
In regulatory wording, the word “shall” signals a duty or requirement, and “shall not” signals a prohibition. When a rule does not use either of those words, it isn’t forcing action or forbidding it—it’s permissive. So, rules described by the absence of “shall” or “shall not” tell you what is allowed or optional, rather than what you must do or must not do. That’s why this item points to permissive rules: they indicate non-mandatory directions or options rather than obligations. If a rule did say “shall” or “shall not,” it would be enforcing a mandatory or prohibited action, not merely allowing something.
