+/**
+ * The <i>Stream Prioritization Object</i> indicates the author's intentions as
+ * to which streams should or should not be dropped in response to varying
+ * network congestion situations. There may be special cases where this
+ * preferential order may be ignored (for example, the user hits the "mute"
+ * button). Generally it is expected that implementations will try to honor the
+ * author's preference.
+ * 
+ * The priority of each stream is indicated by how early in the list that
+ * stream's stream number is listed (in other words, the list is ordered in
+ * terms of decreasing priority).
+ * 
+ * The Mandatory flag field shall be set if the author wants that stream kept
+ * "regardless". If this flag is not set, then that indicates that the stream
+ * should be dropped in response to network congestion situations. Non-mandatory
+ * streams must never be assigned a higher priority than mandatory streams.
