Your idea
Hi there, I noticed when exporting a MusicXML from Musescore 4 that any alteration done to ornaments (either above or below) do not show up in the XML file. This is something I would like if it is possible, please.

I will attach files for the above example below:
Archive.zip
Here is the MusicXML 4.0 documentation for how this should look in the XML once completed:

Please let me know if you have any questions about this.
Problem to be solved
It would allow any "accidental alterations" to an ornament to be visible in the MusicXML export. If the import was also done, then Musescore 4 would also recognize this information.
