Summary0009512: Clarification for configuration transaction support
Description

The following text in the configuration transaction description needs changes:
If the Server does not support transactions it applies the changes immediately and sets applyChangesRequired to FALSE. If the Server supports transactions then the Server creates a new transaction or continues an existing transaction and sets applyChangesRequired to TRUE.

If a server returns applyChangesRequired set to TRUE is NOT a indication that the transaction is supported by the server. Servers returned true long before the transaction concept was introduced.

We need a clear indication that the transaction mechanism is supported by a server. The existence of the CancelChanges is better but in worst case it only indicates that the server loaded a OPC UA 1.05 nodeset but not that the method or the transaction concept is implemented.

Additional Information

It would make sense to have a dedicated transaction chapter instead of hiding this concept in a General section
