Semantics. It is because you have an IMC rating that you have these additional privileges, which are very useful, and historically another important reason for the IMC rating. In other words not mentioning this element fails to give the entire picture.
It's an important distinction though. Some people can take it to mean that the IMC rating is therefore recognised in other other countries, when that is not correct at all.
I know of cases where another country has given consent.
Can you provide more info? That would be very useful to know for everyone with an IMC or contemplating obtaining an IMC.
