What indicates the location of substantial revisions to an order?

The indication of substantial revisions to an order is represented by bold vertical lines. This is a standard practice in many documents and regulatory frameworks, where significant changes are visually demarcated to draw attention. Using bold vertical lines allows readers to quickly identify the areas that have undergone substantial revisions, facilitating easier navigation through the document.

Italicized text often signifies emphasis or a change in terminology but does not specifically indicate substantial revisions. Footnotes are typically used to provide additional information or clarification without altering the main text. Highlighted sections can draw attention to information but are not necessarily reserved for denoting substantial revisions. Thus, bold vertical lines remain the most effective visual cue for showing substantial changes within the context of an order.
