+	//     2.	Additional information may or may not be represented in textual form.
+	//     3.	The semantics of additional error information are specific to the ONU vendor.
+	//     4.	The ONU must not rely on the OLT being able to detect or interpret additional
+	//    		error information.
+	//     5.	Additional error information may occupy only padding bytes (baseline message set)
+	//    		or only uncommitted trailing bytes (extended message set).
+	//     6.	In get, get current data and get next responses, the attribute mask controls the
+	//    		padding definition.
+	//     7.	No additional error information is permitted in responses to start download and
+	//    		end download messages that are directed to multiple target MEs, as indicated by
+	//   		0xFFFF in the target ME identifier.

+	//       decodes the information is available through the Payload() function of the message-type
