609 origin and ctlNum optional?
This tissue has following status: blue
Created: 22 Feb 2008
Category: Issue for edition 2 of this part
Issue: Part 7-3 makes the two control attributes 'origin' and 'ctlNum' optional but 8-1 makes these (mostly) mandatory. It is unclear why an MMS mapping would require these attributes and another mapping (example Web services) would not require these parameters.
Proposal: Either make these attributes optional in 8-1 or mandatory in 7-3.
