Remarks
This watermark describes where the GetEvents operation begins to return events. The watermark that is passed to GetEvents must be the last watermark that was returned to the client. If this is the first call to GetEvents after Subscribe, the watermark that is returned by Subscribe should be passed to GetEvents. If GetEvents has already been called, the watermark that is passed to the next GetEvents call must be the watermark of the last event that is returned from the previous GetEvents call.
If the Watermark property is set with an invalid watermark, an ErrorInvalidWatermark error is returned to the client application.
