delete/add history data between two continuation point read|OPC UA Standard|Forum|OPC Foundation

Hello,

I have question about the behavior of historyReadRaw with valid continuationPoint and reaturnBounds be true.

Suppose we have following history raw data on server side;

Name  Time    Value   StatusCode

D0       5:00     0        Good

D1       5:01     1        Good

D2       5:03     2        Good

D3       5:04     3        Good

If we call HistoryRead service with parameter: returnBounds=true, numValuesPerNode=0, startTime=5:00, endTime=5:03.

We will get three values D0,D1,D2 according to specification.

If we call HistoryRead service with parameter: returnBounds=true, numValuesPerNode=1, startTime=5:00, endTime=5:03.

The first call, we will get value D0 and a continuation point;

The second call, we will get value D1 and a continuation point;

If we delete value D2 OR insert another D4 (Time 5:02, value 4, status Good) before we call HistoryRead service; 

What should we get at the third call?
