2.2.12 Shared Workbooks

The shared workbook infrastructure is used to enable multiple users to make changes to a workbook at the same time and track changes made by certain users. A shared workbook contains a collection of users that currently have the document open and revision logs (section 2.2.12.3) that contain the changes that users have made to the workbook. Each of these logs has a corresponding revision header associated with it and contains either zero or more revision records (section 2.2.12.4) that have been made to the shared workbook since it has been shared. A workbook is a shared workbook if and only if the user names (section 2.1.7.55) stream exist.
