	 *
	 * This API allows you to create readonly documents in VSCode from arbitrary
	 * sources, and works by claiming an uri-scheme for which your provider then
	 * returns text contents. The scheme must be provided when registering a
	 * provider and cannot change afterwards.
	 *
	 * Note how the provider doesn't create uris for virtual documents - its role
	 * is to provide contents given such an uri. In return, content providers are
	 * wired into the open document logic so that providers are always considered.
