Not parsing icloudpd xmp files

[juju4]

Describe the bug

Thanks a lot for the tool.

icloud_photos_downloader generates an xmp from Apple metadata since v1.25.0 (https://github.com/icloud-photos-downloader/icloud_photos_downloader/releases/tag/v1.25.0) but those are not read by exiv2 even if valid image file (read by digikam, feh, browsers...). This prevents import of those metadata in digikam for example.

To Reproduce

$ more /media/path/to/IMG_1029.JPG.xmp

[ok...]

Tested with exiv2 0.28.5 and exiftool 13.10

Expected behavior

metadata should be read correctly and imported when apply

Desktop (please complete the following information):

• OS and version: Linux Fedora 41
• Exiv2 version and source: 0.28.5 from Fedora package

ExifTool is currently not a good validator of XMP, but if you try to write it with ExifTool you will get this:

Error: [minor] Improperly enclosed XMP property: x:xml_doc/rdf:RDF/rdf:Description/xmp:Rating

There are a number of problems with this XMP that are causing this error.

Thanks @boardhead How to fix those problems so metadata can be imported either in photo tool or in image itself?
