FinalCut Pro X exports missing XML tags?

I don't know if this is a Davinci Resolve issue or an issue with the fcpxml adapter, but it seems like there are some XML tags and properties missing in the adapters exports. I compared the adapters export to a video application that supports fcpxml exports that open in Resolve. Making the appropriate changes to the adapters export file allowed me to open it in Davinci Resolve.

These are the changes I had to make.

- Added standalone="no" to
- Added an empty tag under the end tag. Made sure the closing tag was in the appropriate place
- Add an tag under the tag. Made sure the project name matched what was in the tag and the closing tag was in the appropriate place.

Here is an opentimelineio export sample

And here is an export I did with the LumaFusion video editor.

I compared the two above files to find the issues.

Start with the fcpxml adapter export and compare its generated XML with the linked OpenTimelineIO and LumaFusion samples. Verify whether the XML declaration, library, and event elements are required for DaVinci Resolve, then confirm that the adapter output opens correctly there with the project name preserved.
