As part of the UBL 2.5 work we created a "Deprecation Policy" to mark elements that the TC will report from a future 3.x UBL version and is discouraging people to use these elements going forward in the 2.5 and later versions.

To assist people with this .. we could create XSDs that don't contain these elements .. so that people can use those XSDs if they wish to see what the impact will be on their implementations.

This ticket is to track the discussion about whether we should do this and if it should be part of the 2.5 specs or a separate committee note?
