How do you letter annexes?

Annexes are typically labeled using uppercase letters in alphabetical order, starting with "A." For example, the first annex would be designated as "Annex A," the second as "Annex B," and so on. If there are multiple annexes, they may also be numbered (e.g., "Annex A1," "Annex A2") for further categorization. It's important to maintain consistency in formatting throughout the document.
