         This stream is a superior alternative (higher resolution or otherwise)
         of the given stream. It should be preferred if the decoder is capable
         of decoding it.
+    "Depends"
+        v (stream id)
+        This stream depends on the specified stream. That is if its

+        dependancies for scalability for example.

         instead? is there some other unique way to identify fonts?
