+By default, byte order of a basic type is the byte order described in

 TSDL meta-data representation:
 
   byte_order = native OR network OR be OR le;	/* network and be are aliases */
 
+The "native" keyword selects the byte order described in the trace
+description. The "network" byte order is an alias for big endian.
+
+Even though the trace description section is not per se a type, for sake
+of clarity, it should be noted that "native" and "network" byte orders
+are only allowed within type declaration. The byte_order specified in
+the trace description section only accepts "be" or "le" values.
