	 * The @attribute string should be formatted with specific keys separated

	 * ## Examples of file attribute matcher strings and results
	 *
	 * - `"*"`: matches all attributes.
	 * - `"standard::is-hidden"`: matches only the key is-hidden in the
	 * standard namespace.
	 * - `"standard::type,unix::*"`: matches the type key in the standard
	 * namespace and all keys in the unix namespace.
	 *
	 * Params:
	 *     attributes = an attribute string to match.

	 * Return: a #GFileAttributeMatcher
