Summary0005633: SemanticChange Bit reset
Description

The status bit (14:14) for SematicsChanged has a description of when it is set, but the description does not include anything about when it is reset. I would propose that the text be updated to add that, this bit is just set on one value in the subscription and then cleared.

Added the follwing clarification to StructureChanged and SemanticsChanged.

The bit is set on one data change Notification per MonitoredItem that samples values at the time the structure change happened. If the data change notification is deleted because of a queue overflow, the bit must be set on the next data change notification in the queue.

Added in OPC 10000-4 - UA Specification Part 4 - Services Draft 1.05.08.docx
