Shall: Indicates a mandatory requirement. Designers shall implement such mandatory requirements
to ensure interchangeability and to claim conformance with the specification.
Should: Indicates a strong recommendation but not a mandatory requirement. Designers should give
strong consideration to such recommendations, but there is still a choice in implementation.
Reserved: Indicates a bit, byte, field, and value that are set aside for future standardization or other
usage. A reserved bit, byte, or field shall be set to zero unless specified differently in this
specification, or in accordance with a future extension to this or other standards. Hosts and
