I am not finding anywhere in the DFDL spec that says explicitly what happens during unparsing when a decimal value is given to the unparser, and its rep is binary, and the BDVP is not sufficient to remove the decimal point from the value. This is surely a processing error, because the spec states in section 13.7.1 "When unparsing a binary number (packed decimal or twos-complement) and excess precision is supplied in the Infoset no rounding occurs. It is a processing error."
