+ * Class FeaturePolicy is a simple helper which allows applications to
+ * modify the Feature-Policy sent by Nextcloud. Per default only autoplay is allowed
+ * from the same domain and full screen as well from the same domain.
+ *
+ * Even if a value gets modified above defaults will still get appended. Please
+ * notice that Nextcloud ships already with sensible defaults and those policies
+ * should require no modification at all for most use-cases.
