2.2.12.1 User Log

The user log contains the set of users who currently have the workbook open. BrtCUsr (section 2.4.344) specifies the number of BrtUsr (section 2.4.844) records that the user log contains. Each BrtUsr record corresponds to a user that currently has the workbook open. The guid field of BrtUsr maps to the guid field of BrtRRHeader (section 2.4.771) to specify the latest revision header and revision logs (section 2.2.12.3) pair that the user is currently synchronized to.
