+ *
+ * @brief Implementation of the data structure used to pass parameters
+ * to the encoder.
+ *
+ * The parameters data structure is currently a simple struct, but
+ * fields may be added, removed, or replaced. A version number is
+ * included in the parameters data structure to allow decoders to
+ * adapt to changes.
+
+ * It is contemplated that future inplementations may use a dictionary
+ * of key-value pairs which would allow the decoder to determine whether
+ * a parameter is present.
