The `aria-errormessage` attribute is not allowed on a `<label>` element that points to a form control through its `for` attribute.

`aria-errormessage` takes the `id` of the element holding the error text for a form control. Assistive technology announces that text when the control is marked invalid with `aria-invalid="true"`. Both attributes describe the control's value, so both go on the control.

A `<label>` with a `for` attribute is associated with the labelable element whose `id` matches, and its text becomes that element's accessible name. The label has no value and no validity state of its own, so an error reference on it has nothing to describe. The control it names still has no error message attached, and a screen reader user who reaches the invalid field hears no error.

Move `aria-errormessage` from the `<label>` to the control named in `for`, and set `aria-invalid="true"` on the control while its value fails validation. If the `<label>` wraps the control instead of using `for`, the validator reports the same mistake with a different message, saying the `<label>` is an ancestor of a labelable element.

## Invalid example

```html
<input type="checkbox" id="terms" name="terms" required>
<label for="terms" aria-errormessage="terms-error">I accept the terms of service</label>
<span id="terms-error">You must accept the terms to continue.</span>
```

## Valid example

```html
<input type="checkbox" id="terms" name="terms" required aria-invalid="true" aria-errormessage="terms-error">
<label for="terms">I accept the terms of service</label>
<span id="terms-error">You must accept the terms to continue.</span>
```
