Final answer:
Change of Transmittal is typically noted through specific codes or identifiers in a formal documentation or project setting.
Step-by-step explanation:
Changes of Transmittal in a document or a project are typically noted through specific codes or identifiers. A coding system is often used to indicate that one portion of the documentation is related to or changes another portion. This approach ensures that everyone involved can follow the changes without confusion. For example, some organizations might use a series of letters or numbers to reference different types of changes or areas within a project. While color-coding can be effective in some contexts, such as noting annotations or emphasizing certain text features, when it comes to official documents and Transmittals, more formal methods such as specific codes are usually preferred to maintain clarity and formality.
