These definitions MUST be used when a rule includes a term in all caps, and SHOULD be used when a rule includes a term otherwise. Earlier definitions take precedence over later ones.

MUST NOT, MAY NOT, SHALL NOT, ILLEGAL, PROHIBITED: Performing the described action violates the rule in question. 3. SHOULD NOT, DISCOURAGED, DEPRECATED: Before performing the described action, the full implications of performing it should be understood and carefully weighed. 4. CAN X ONLY IF Y: Equivalent to "CANNOT X unless Y". Similar for (MUST, MAY, SHALL, SHOULD) X ONLY IF Y. 5. MUST, SHALL, REQUIRED, MANDATORY: Failing to perform the described action violates the rule in question. 6. SHOULD, ENCOURAGED, RECOMMENDED: Before failing to perform the described action, the full implications of failing to perform it should be understood and carefully weighed.
