     * The special key `'*'` as a tag name defines property names allowed on all
     * elements.
     *
     * The special value `'data*'` as a property name can be used to allow all
     * `data` properties.
     *
     * For example:
     *
     * ```js
     * attributes: {
     * 'ariaDescribedBy', 'ariaLabel', 'ariaLabelledBy', …, 'href'

     * 'width'
     * ]
     * }
     * ```
     *
     * Instead of a single string in the array, which allows any property value
     * for the field, you can use an array to allow several values.
     * For example, `input: ['type']` allows `type` set to any value on `input`s.
     * But `input: [['type', 'checkbox', 'radio']]` allows `type` when set to
     * `'checkbox'` or `'radio'`.
     *
     * You can use regexes, so for example `span: [['className', /^hljs-/]]`
     * allows any class that starts with `hljs-` on `span`s.
     *
     * When comma- or space-separated values are used (such as `className`), each
     * value in is checked individually.
     * For example, to allow certain classes on `span`s for syntax highlighting,
     * use `span: [['className', 'number', 'operator', 'token']]`.
     * This will allow `'number'`, `'operator'`, and `'token'` classes, but drop
     * others.
