🟠 [RGAA 11.10] Input validation issues

[jbpenrath]

Bug Report

Problematic behavior
Across multiple forms:

• Required fields are not indicated to users
• Error messages are not programmatically linked to their respective fields
• Some error messages lack actionable information (e.g. the email field on the import page does not show expected format on error)

Expected behavior/code
Required fields must be clearly indicated. Error messages must be linked to fields via aria-describedby and provide actionable guidance including examples.

Steps to Reproduce

1. Submit the label name form with an empty required field — no indication that the field is required
2. Trigger a validation error — error message is not announced by screen reader
3. On the import page, enter an invalid email — error does not indicate expected format

Environment

• RGAA Criterion: 11.10
• Severity: 🟠 Major

Possible Solution

• Indicate required fields in <label> text or via introductory text (e.g. "* Required fields")
• Link error messages to fields via aria-describedby pointing to the error's id
• Import page email error → "Invalid email address. Example: j.doe@gmail.com"
