Sets an internal flag indicating if workflow notification will be sent out during the current action (check in, update, resubmit, and so on).
The suppression is on both email and updates to the workflow in queue. An additional use for this function is to suppress workflow notification until after a document has been converted. This prevents a document from advancing out of the auto-contributor workflow step when the document finishes a conversion.
Takes one parameter, the internal flag. If set to 1 (TRUE), notifications are not suppressed. If set to 0 (FALSE), notifications are suppressed.
