Understand what is an MLT template file that allows you to manage variables and conditional tags at a book level in Adobe FrameMaker.
Managing variables and conditional tags manually across multiple documents in a book map can be time-consuming and error-prone. To simplify this process, FrameMaker provides a book-level template (.MLT file) that allows you to pull variables and conditional tags from the individual documents of a book file and manage them through one centralized location– within the MLT file.
