UPOS1162 — See issue UPOS1151-11, SmartCardRW Status Diagram Confusing, readData Method Handling Unclear

I think the solution should not be to remove DataEvent and ErrorEvent from the status diagram. Both events are necessary to signal availability of data or reader problems to the application.
Instead, the text in chapter 37.5 after Input should be changed as follows:

Remove the first sentence "The application must invoke the readData method in order to request data from the smart card."

To make it more clear, the arrows marked with "DataEvent()" and "readData(action, count, data)" should be exchanged.
