RevisionFlag

RevisionFlag indicates the revision status of element; the default is that element hasn't been revised. RevisionFlag is intended only for simple revision management: to track the entire history of a document use a proper revision control system. Use RevisionFlag for indicating changes from one version to the next, no more. As you and your interchange partners review a particular revision, you can use the Off value to indicate that a subelement of a Changed, Added, or Deleted element has been agreed upon.
