+ * @class TAO_CDR_Encaps_Codec
+ *
+ * @brief Implementation of a CDR encapsulation coder/decoder
+ * (Codec).
+ *
+ * This coder/decoder (Codec) class encodes and decodes data to and
+ * from a CDR encapsulation, respectively.  It is useful for creation
+ * of octet sequences that contain CDR encapsulations.  Those octet
+ * sequences can then be placed in a IOP::ServiceContext or an
+ * IOP::TaggedComponent, for example.
+ *
+ * @note This Codec should not be used for operations internal to the
+ * ORB core since it uses interpretive marshaling rather than compiled
+ * marshaling.
