Proper Handling of Roman Numerals in Accessible Content

In many cases, Roman numerals are used as the sole identifier for chapters or sections of a book or other written work. For example, a chapter may be titled "IV" instead of "Chapter 4". However, this poses a challenge for users who rely on assistive technology to access digital content. Screen readers and other assistive devices may interpret "IV" as two separate letters ("I" and "V"), making it difficult for these users to understand the structure of the content.

One possible solution would be to use an aria-label or another accessible attribute to provide an alternative text description of the Roman numeral. For example, a chapter entitled "IV" could have an aria-label of "Chapter 4: Title of Chapter". This would allow assistive technology to correctly announce the number as "Chapter 4" while still preserving the Roman numeral as the visual identifier.

I would like to request guidance on the proper way to handle Roman numerals in accessible content, particularly when used as chapter or section titles. Thank you for your attention to this matter.
