Repro

In MuseScore 4 open a chart with chords.

File/Export:

• Main score
• Format: Music XML
• File type: Uncompressed (*.musicxml)

Click "export..."

Rename the exported file to "name.xml"

Issue 1: JJazzLab doesn't support "musicxml" extension.

Open jjazzlab and choose File > Import Songs...

open "name.xml".

Issue 2: Receive the following:

nu.xom.ParsingException: The markup declarations contained or pointed to by the document type
declaration must be well-formed. at line 1, column 2 in http://www.musicxml.org/dtds/partwise.dtd

Actually this is not a bug, it's just that the referenced dtd http://www.musicxml.org/dtds/partwise.dtd in your file is not available anymore. I found other people complaining about this on MuseScore forum.

W3C has put the dtd files on GitHub, so I replaced the original dtd by https://raw.githubusercontent.com/w3c/musicxml/v4.0/schema/partwise.dtd then JJazzLab successfully imported your file.

I found a way to provide the dtd file locally, so you won't have to update the file.
