Edit note
An edit note is a particular type of XLink (a note) attached to a specific change in a fragment (an edit).
The purpose of edit notes is to explain the reason for the change in the document. For example, if a document was edited to address a typographical error, an edit note can be made to mention this.
Edit notes appear to the right of the edited fragment when viewing a document. They are also displayed when viewing the change history of the fragment.
Although they are attached to document fragments, unlike comments, they do not persist after the fragment has been edited.
