FormHelper ARIA integration for validation error states

CakePHP's FormHelper provides a standardized method for generating HTML5 inputs and associating them with labels. While custom attributes like aria-label can be passed through the options array, the framework's automatic error rendering typically inserts validation messages into the DOM without a native, dynamic link to the input's accessibility state.

To meet WCAG 2.1 standards, input fields should ideally utilize aria-invalid="true" and aria-describedby when a validation error is present. Currently, this requires manual implementation within the template or a custom helper override to ensure the generated error container ID matches the input attribute.

• Is there a configuration within the FormHelper to automatically toggle aria-invalid based on the model's error state?
• How can aria-describedby be dynamically mapped to the automatically generated error message IDs without manually defining IDs for every field?
