Rule A2-7-5 (required, implementation, non-automated)
Comments shall not document any actions or sources (e.g. tables, figures, paragraphs, etc.) that are outside of the file.
Rationale
Commenting only actions and sources that are inside a particular file reduce dependencies among files. Comments in a file will require changes only when content of the file reworked. Note: This rule does not affect valid assumptions or preconditions for entities within the file.
