We have a registration form where all fields are required except for one. Our BA doesn't want to show any required signs (required, *, etc.) and wants to have (Optional) for the optional field.
His reasoning - everything is required so why add those indicators.

Of course when user submits the form those required fields will show error if empty.
Is this an accessibility violation? Would the easy fix be to not add "required" attribute but set "aria-required" to true?
