Guidance
Interpret the key words MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD, SHOULD NOT, RECOMMENDED, MAY, and OPTIONAL as described in RFC 2119.
Authoritative guidance using these key words appear in admonitions titled “Guidance”, like above. An explanation of the rationale for the rule plus supporting material appears after in separate paragraphs, like this. Usually, each rule falls under its own subheading, which facilitates cross-referencing. Top-level headings provide a content summary or a quick reference.
