Using the specified sessionId value, an exclusive lock is obtained for the session on the version. The exclusive lock can only be obtained if no other shared or exclusive locks are present and the session currently holds a shared lock. The exclusive lock ensures read and write isolation for the session holding the lock. You can downgrade the exclusive lock to a shared lock using the stopEditing operation.


Review the read and edit session requirements for version resource operations.
