Yeah, I kind of prefer that, we potentially allow non-string values to occur multiple times, so I'd say let's allow string values as well, even if that is not common. (I am not sure if it is strictly invalid or just uncommon).

Are there files in the wild that do this? Being stricter is often the
better option when it comes to MXF. A muxer that outputs metadata more
than once might be doing something wrong.

I am not sure, but I wanted to be safe rather than sorry, because it is not unusual in MXF to repeat certain metadata in the footer partition which is already present in the header, and I did not want to take the risk of rejecting a valid file.

Marton
