+## Applicability
+
+This rule applies to any [WAI-ARIA global state or property][global] that is specified on an [HTML or SVG element][namespaced element] that is [included in the accessibility tree][].
+
+## Expectation
+
+The test target is not [prohibited][] for the [semantic role][] of the element on which it is specified.
+
+## Background
+
+The presence of prohibited ARIA attributes is often the result of a developer using an incorrect role, or a misunderstanding of the attribute. These attributes are ignored by browsers and other assistive technologies. This often means that a state or property which should exist is missing.
+
+In HTML, there are language features that do not have corresponding implicit WAI-ARIA semantics. As per [ARIA in HTML](https://www.w3.org/TR/html-aria/), those elements can have [global states or properties][global]. Some of those elements can also have [inherited][], [supported][], or [required][] [states][state] or [properties][property] that correspond to a [WAI-ARIA role](https://www.w3.org/TR/wai-aria-1.2/#introroles). For example, the `audio` element has no corresponding ARIA semantics but it can have [inherited][], [supported][], or [required][] [states][state] or [properties][property] of the [`application` role](https://www.w3.org/TR/wai-aria-1.2/#application).
+
+### Assumptions
+
+There are no assumptions.
+
+### Accessibility Support
+
+Browsers and assistive technologies behave differently when prohibited attributes are used. Some may assign a role so that the property is available to assistive technologies, where others ignore the attribute.
+
+Implementation of [Presentational Roles Conflict Resolution][] varies from one browser or assistive technology to another. Depending on this, some elements can have a [semantic role][] of `none` and their attributes fail this rule with some technologies but users of other technology would not experience any accessibility issue.

+## Examples
+
+### Passed
+
+#### Passed Example 1
+
+This generic `div` element is allowed the global `aria-live` property.
+
+```html
+
I like Bananas
+```
+
+#### Passed Example 2
+
+This `a` element with an [implicit role][] of `link` is allowed the `aria-label` property.
+
+```html
+€100 / €1
+```
+
+#### Passed Example 3
+
+This `div` element is allowed the `aria-braillelabel` property because its [explicit role][] of `heading` does not prohibit this.
+
+```html
+
+ I ❤️ Bananas
+
+```
+
+### Failed
+
+#### Failed Example 1
+
+The `aria-label` property is [prohibited][] for an element with a `generic` role.
+
+```html
+
€100 / €1
+```
+
+#### Failed Example 2
+
+The `aria-labelledby` property is [prohibited][] for an element with a `paragraph` role.
+
+```html
+
I like bananas
+
🧑 ❤️ 🍌🍌
+```
+
+#### Failed Example 3
+
+The `aria-braillelabel` property is [prohibited][] for an element with a `button` role.
+
+```html
+
I ❤️ Bananas
+```
+
+#### Failed Example 4
+
+The `aria-roledescription` property is [prohibited][] for an element with a `generic` role.
+
+```html
+
I like bananas
+```
+
+#### Failed Example 5
+
+The `aria-brailleroledescription` property is [prohibited][] for an element with a `none` role.
+
+```html
+
I like bananas
+```
