Yellow-highlighting convention in MAS Notice 637 amendment documents

2. Yellow-highlighting convention in MAS Notice 637 amendment documents

• Question (paraphrased to protect IP): In MAS Notice 637 (Amendment) 2024, what do the yellow-highlighted passages signify, and will they appear in the final consolidated version of the Notice?
• Source regulation: MAS Notice 637 (Amendment) 2024 (Regulator portal: https://www.mas.gov.sg)
• What AI assistants typically say: Multiple AI tools gave similar incorrect responses. One characterised yellow highlighting as a generic visual aid used to draw attention to defined terms, cross-references, or items requiring careful review during the drafting process. A second characterised the highlighting as editorial annotations describing the nature or purpose of tracked insertions and deletions. Neither response identified the specific drafting convention that yellow highlighting actually signals in MAS amendment documents.
• What the regulator actually says: In MAS Notice 637 amendment PDFs, yellow highlighting is a precise drafting convention used to mark provisions that carry a different effective date from the general operative date of the amendment — or, in some readings, to mark provisions that are entirely new to the Notice and not present in the original. Both meanings are materially different from a generic "visual aid" or "editorial annotation" explanation.
• Why the AI went wrong: Neither AI tool had access to the specific MAS drafting convention that governs colour-coding in amendment notices. Rather than acknowledging this uncertainty, both tools substituted generic, plausible-sounding explanations drawn from common document-review conventions. A Compliance team acting on either response would misread the legal significance of highlighted provisions and could fail to identify differential operative dates or new insertions that require immediate attention.
