In which markings are parentheses utilized?

The use of parentheses is specifically associated with portion markings, which indicate the classification level of individual sections or portions of a document. This practice allows for clear identification of the classification status of each part of the text, ensuring that readers understand the level of sensitivity for different segments, even if the entire document is classified at a different level.

For example, in a classified document, specific sentences or paragraphs may be marked to show that they are classified at a higher or lower level than the document itself. Utilizing parentheses helps to visually separate these markings and clearly communicate the classification status.

In contrast, banner markings and file markings serve different purposes. Banner markings typically designate the overall classification of an entire document at the top, while file markings are used on cover sheets or file labels but do not require the use of parentheses. Understanding these distinctions clarifies why parentheses are relevant specifically in the context of portion markings.
