+		An OpenXR action.
+	</brief_description>
+	<description>
+		This resource defines an OpenXR action. Actions can be used both for inputs (buttons/joystick/trigger/etc) and outputs (haptics).
+		OpenXR performs automatic conversion between action type and input type whenever possible. An analogue trigger bound to a boolean action will thus return [code]false[/core] if the trigger is depressed and [code]true[/code] if pressed fully.
+		Actions are not directly bound to specific devices, instead OpenXR recognises a limited number of top level paths that identify devices by usage. We can restrict which devices an action can be bound to by these top level paths. For instance an action that should only be used for hand held controllers can have the top level paths "/user/hand/left" and "/user/hand/right" associated with them. See the [url=https://www.khronos.org/registry/OpenXR/specs/1.0/html/xrspec.html#semantic-path-reserved]reserved path section in the OpenXR specification[/url] for more info on the top level paths.
+		Note that the name of the resource is used to register the action with.

+		Collection of [OpenXRActionSet] and [OpenXRInteractionProfile] resources for the OpenXR module.
+	</brief_description>
+	<description>
+		OpenXR uses an action system similar to Godots Input map system to bind inputs and outputs on various types of XR controllers to named actions. OpenXR specifies more detail on these inputs and outputs than Godot supports.
+		Another important distinction is that OpenXR offers no control over these bindings. The bindings we register are suggestions, it is up to the XR runtime to offer users the ability to change these bindings. This allows the XR runtime to fill in the gaps if new hardware becomes available.
+		The action map therefor needs to be loaded at startup and can't be changed afterwards. This resource is a container for the entire action map.

+		Collection of [OpenXRAction] resources that make up an action set.
+	</brief_description>
+	<description>
+		Action sets in OpenXR define a collection of actions that can be activated in unison. This allows games to easily change between different states that require different inputs or need to reinterpret inputs. For instance we could have an action set that is active when a menu is open, an action set that is active when the player is freely walking around and an action set that is active when the player is controlling a vehicle.
+		Action sets can contain the same actions, or actions with the same name, if such action sets are active at the same time the action set with the highest priority defines which binding is active.
+		Note that the name of the resource is used to identify the action set within OpenXR.

+	</brief_description>
+	<description>
+		The OpenXR interface allows Godot to interact with OpenXR runtimes and make it possible to create XR experiences and games.
+		Due to the needs of OpenXR this interface works slightly different then other plugin based XR interfaces. It needs to be initialised when Godot starts. You need to enable OpenXR, settings for this can be found in your games project settings under the XR heading. You do need to mark a viewport for use with XR in order for Godot to know which render result should be output to the headset.

+
+		Also Godot only creates a swapchain for the main output.
+		OpenXR will require us to create swapchains as the render target for additional viewports if we want to use the layer system
+		to optimise text rendering and background rendering as OpenXR may choose to re-use the results for reprojection while we're
+		already rendering the next frame.
+
