Final Cut Pro mishandles `format` of PDF files in FCPXML

[latenitefilms]

Apple Feedback Assistant ID: FB22046427

DESCRIBE THE BUG:
Final Cut Pro v12.0.0 can incorrectly output invalid FCPXML, that does not pass its own Document Type Definition (DTD), when working with PDF files.

This has been reported by a user of ScriptStar:

latenitefilms/ScriptStar#7

We are also tracking it in our own FCPXMLKit bug tracker:

https://github.com/CommandPost/FCPXMLKit/issues/67

I have sent the following information to Apple via FB22046427 and have chased up the Final Cut Pro team directly:

One of our customers has sent us a FCPXML exported from a Final Cut Pro v12 library, which has a very unexpected output.

This FCPXML doesn’t seem to be able to be reimported into Final Cut Pro.

When attempting to import we get:

The XML document sent from application “Final Cut Pro” could not be imported.

The media file cannot be imported. An offline clip was not created because of insufficient data. (frameDuration=<empty>: /fcpxml[1]/resources[1]/format[16])

No such file or directory

There’s a few weird things in it, for example - looking at the formats:

It seems there might be bugs/regressions in the FCPXML handling of PDFs?
