Populating the subkeyword MDLP5S with the Scheme update date using MailStream Plus

Product Affected:  MailStream Plus™

The MailStream Plus™ (MSP) subkeyword MDLP5S part one which is 'scheme update date' is not currently used for anything.
It used to be used for a value in the Mail.dat .mpu file prior to  But it was deleted at that time. 
It has always been recommended to leave this blank so the MSP software would populate this Scheme update date value.
Note: We discourage the use of this field.
The other values are still being used:
  • LOT Database Date populates SEG-1116
  • Line of Travel forward or reverse code populates  SEG-1122
