Summary0002667: Description of Continuation Point (6.3) does not match general concept
Description

OPC UA has the concept of a max size list of continuation points per session. As long as the max size is not exceeded, the continuation points stay valid as long they are not used by the client. A server may in addition time out continuation points.

Part 11 - 6.3 Continuation Points - defines
If the Client specifies a ContinuationPoint that does not correspond with last returned ContinuationPoint from the Server, then the Server shall return a Bad_ContinuationPointInvalid error.

This sentence is wrong. This would make parallel execution of HistorRead calls for different nodes impossible.

The sentence must be changed to:
If the Client specifies a ContinuationPoint that is not longer valid, then the Server shall return a Bad_ContinuationPointInvalid error.

Fixed in 1.03 draft 03
Removed the part of the sentence suggested and made it "is no longer valid" to match with how continuation points work in the rest of the specifications.
