Note is designed to be an inherent part of the DDI passing along with a DDI object over its lifetime. It is not intended to replace formal extension mechanisms. Formal extension should be used whenever a locally used object needs to be added to the schema. However, run-time extension needs may arise and Note can be used to capture the required metadata and associate it with the appropriate object.
This example shows a production process note, a work-around, and a proprietary content note.
