+// Header for key system names. Keep these separate from some of our other
+// EME utils because want to use these strings in contexts where other utils
+// may not build correctly. Specifically at time of writing:
+// - The GMP doesn't have prefs available, so we want to avoid utils that
+//   touch the pref service.
+// - The clear key CDM links a limited subset of what normal Fx does, so we
+//   need to avoid any utils that touch things like XUL.
