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 beside the document, on the right-hand side of the edited fragment when viewing a document. They are also displayed when viewing the change history of the fragment.
