6.2.7.1 PublisherId

Removed
The unique identifier for an OPC UA Application is the ApplicationUri. It is recommended to use the ApplicationUri String as a default PublisherId for broker based transport protocols.

Added
The default PublisherId for broker based transports equals the PublisherId for datagram transport protocols but the DataType is UInt64 for UADP message mapping and String for JSON message mapping. For the String, the UInt64 value is converted to a String. The PublisherId may used in message headers, as part of a QueueName or as a client identifier for the broker connection. In these cases the size of the PublisherdId and the characters used in the PublisherId may have limitations or impact to the communication performance.
