Disallow aria-label misuse (aria-label-misuse)

aria-label is used to set the label of an element when no native text is present or non-descriptive. The attribute can only be used on the following elements:

Additionally, this rule ignores elements which explicitly declare an aria-label attribute. See the section on custom components below.

Custom components

When using custom components and you expect consumers to set aria-label on your component you need to explicitly declare the aria-label attribute:

import { defineMetadata } from "html-validate";

export default defineMetadata({
  "awesome-component": {
    attributes: {
      "aria-label": {},

The mere presence of aria-label declaration ensures this rule will allow aria-label to be specified.
