I'm trying to import a MusicXML 2.0 file that was exported from another app into Finale. It imported perfectly into Finale v26 on an Intel Mac about a year ago. Today, when I tried to import it into Finale v27 (on Apple Silicon), it threw a bunch of validation errors and then gave up and did the best it could (which was absolutely terrible). In the spirit of investigation, I uninstalled v27 and reinstalled v26. It failed again the same way.
The DOCTYPE declaration at the top of the file reads <!DOCTYPE score-partwise PUBLIC "-//Recordare//DTD MusicXML 2.0 Partwise//EN" "http://www.musicxml.org/dtds/partwise.dtd"> – and it's clear that Finale is reaching out to that URL to download the DTD to validate the file against. However, from poking around the Internet Archive's Wayback Machine, it seems all the content disappeared from www.musicxml.org sometime between October 2022 and May 2023.
I have years of experience dealing with XML, XML Schema, and DTDs as a software developer, but I can't seem to find any publicly available version of the MusicXML 2.0 DTD that I can point this file at and import it successfully. I've tried scraping the old ones off the Internet Archive, but no luck.
I thought every version of MusicXML was backward compatible, so I also tried pointing it at a newer version's DTD or XML Schema. Didn't get anywhere that way, either.
This is unfortunately the only copy of this score that I have, and I'd really like to get it back into Finale.
Any advice would be greatly appreciated.
