OK, I see that, but the notes in the Single ILR spec state that code 46 should be replaced by code 45. If this is done in an MIS system that will initially produce flat files then the LIS will not be able to convert it. Then when the switchover is made to the XML output the data in the MIS system will need chaging to produce a correct XML file.
If, as you are saying the LIS will convert code 46 then why does the specification need the note?
