XMP parser throws error: Duplicate property or field node 'pdf:Producer' (203)

Is there a way to tell XMPMetaFactory.ParseFromBuffer to be less strict during validation? What could be the workaround?

I failed to find other free XMP parser libraries. The only thing that comes to my mind is to serialize XMP to string, parse it into XDocument, update it, serialize back to string and call PdfDocument.SetXmpMetadata.

Example:
