It seems to use a non-standard chunk outside of the INFO metadata list
chunk, so I don't think that any other application besides BWF MetaEdit
will parse it.

I think Wavelab (since at least 8.5 and up to the current version) can also read and write that chunk so it must be standardised in some way.

I t would be useful to be able to do be able to read and write this tag, is it possible to make a feature request?

It seems to just tack on some data to the end of the file.
