The text in this Standard is divided into normative and informative categories. Unless documented otherwise, any feature shall be implemented as specified by the normative text describing that feature in this Standard. Text marked informative (using the mechanisms described in §7) is for information purposes only. Unless stated otherwise, all text is normative.

Use of the word “shall” indicates required behavior.

Any behavior that is not explicitly specified by this Standard is implicitly unspecified (§4).
