Description
Describe the bug
Open an older MusicXML v2.0 file. Musescore reports invalid format and cannot open.
To Reproduce
Steps to reproduce the behavior:
- Open attached mxl file.
Clementi11.zip
Expected behavior
The file should import fine. Other notation software such as Finale opens it without problems.
Platform information
Windows 11

Research direction
Start by reproducing the failure with the attached Clementi11.zip file and inspect the MusicXML import path that handles the .mxl extension. Compare the behavior for the same older MusicXML v2.0 content under the expected extensions. Done means the attached file imports successfully instead of reporting an invalid format.
